GPT-4 is amazing

[Theo Gottwald]

Before i start let me add that the difference between GPT 3.5 - which is free - and GPT-4 which is paid is really large. This picture may not be totally accurate but GPT-4 can really help in debugging, pretty-printing, code-conversion, it will make repeating tasks for you. While GPT 3.5 is more a toy in that case and will not be of much help in coding -yet it can help with rewriting the manual.



So if you want an coding assistant you need to get GPT-4 and this means you pay $20 to Open AI - which is what i do.

Or you buy it here and do "Pay per type":

I want you to act as a software developer. I will provide some code enclosed in ## and you will check it line by line for mistakes. Before we start make a list with the important things that you will check for. The code will be Powerbasic. Please confirm you understand and ask if you have questions.
Please only show me errors and a improved version.

Following some Subprogramms, first my original version and second the "improved Version" using GPT4.

Original my programming style:
' GetVitualDesktop-Rect-Size or Workarea-Size, if wa=1 then result is size of workarea
'
SUB WR_CV(BYREF xs AS LONG, BYREF ys AS LONG,OPT BYVAL wa AS LONG)
 LOCAL T01,T03,T04,T05,T06 AS LONG
 LOCAL r AS rect
 IF (wa<>0) THEN  GOTO war
 T01=GetSystemMetrics(%SM_CMONITORS)
 xs=MAX&(GetSystemMetrics(%SM_CXFULLSCREEN),GetSystemMetrics(%SM_XVIRTUALSCREEN))
 ys=MAX&(GetSystemMetrics(%SM_CYFULLSCREEN),GetSystemMetrics(%SM_YVIRTUALSCREEN))
 SELECT CASE AS LONG T01
    CASE 0,1:xs=GetSystemMetrics(%SM_CXFULLSCREEN):ys=GetSystemMetrics(%SM_CYFULLSCREEN):GOTO enx
    CASE 2,3:xs=0:FOR T03=1 TO T01:WR_CZ(T03,T04,T05,T06):ys=MIN&(ys,T05):xs=xs+T04:NEXT T03
    CASE ELSE

    war:

Here is another Sample, see how GPT-4 even assumes what certain Macros will do.

Orginal Code:
##
SUB WR_CW(BYVAL T01 AS LONG,BYVAL T02 AS LONG,BYVAL T03 AS LONG,BYVAL T04 AS LONG,BYVAL T05 AS LONG)
 REGISTER x AS LONG,y AS LONG
 LOCAL r AS rect
 LOCAL xs,ys AS LONG
 IF (GetWindowRect(T01,r)=0) THEN GOTO enx
 WR_MI(r,x,y,xs,ys)
 IF T02=-1 THEN T02=x
 IF T03=-1 THEN T03=y
 IF T04=-1 THEN T04=xs
 IF T05=-1 THEN T05=ys
 MoveWindow T01,T02,T03,T04,T05,%True
 enx:
END SUB
##

Follows the rewritten Code:

In the provided code, there are several areas that can be improved for clarity, maintainability, and best practices:

The comments at the top are missing. It's good practice to include a brief description of what the subroutine does.

The variable names T01, T02, T03, T04, T05, xs, and ys are not very descriptive. It's good practice to use meaningful names for variables and parameters.

The use of GOTO is generally discouraged as it can make the code less readable and harder to maintain. It's better to use structured control statements like IF, ELSE, etc.

The subroutine lacks error handling. It's good practice to include error handling to deal with unexpected situations.

The use of WR_MI function is unclear. Make sure it is defined somewhere in the code.

Here's an improved version of the subroutine:

' MoveWindowToPosition - Moves and resizes a window.
' hWnd - Handle to the window to be moved.
' xPos - The new x-coordinate of the window.
' yPos - The new y-coordinate of the window.
' width - The new width of the window.
' height - The new height of the window.
' Note: Passing -1 for xPos, yPos, width, or height will keep the current value.
SUB MoveWindowToPosition(BYVAL hWnd AS LONG, BYVAL xPos AS LONG, BYVAL yPos AS LONG, BYVAL width AS LONG, BYVAL height AS LONG)
    LOCAL windowRect AS RECT
    LOCAL currentX, currentY, currentWidth, currentHeight AS LONG
   
    ' Get the current position and size of the window
    IF GetWindowRect(hWnd, windowRect) = 0 THEN
        ' Handle error
        EXIT SUB
    END IF
   
    ' Assuming WR_MI is a function that gets window dimensions
    WR_MI(windowRect, currentX, currentY, currentWidth, currentHeight)
   
    ' Set the new position and size
    IF xPos = -1 THEN xPos = currentX
    IF yPos = -1 THEN yPos = currentY
    IF width = -1 THEN width = currentWidth
    IF height = -1 THEN height = currentHeight
   
    ' Move the window
    MoveWindow hWnd, xPos, yPos, width, height, %True
END SUB

Changes made:

Added a descriptive comment at the top explaining what the subroutine does.
Changed the parameter and variable names to be more descriptive.
Replaced the GOTO statement with structured control statements.
Added error handling.
Assumed WR_MI is a function that gets window dimensions (it should be defined elsewhere in the code).

Ok, now lets give him ASM-Code.

So here is the response:

The provided code is a PowerBASIC function that uses assembly language instructions to perform a binary search for a substring within a string. Here are a few areas that can be improved for clarity, maintainability, and best practices:

The comments at the top could be more descriptive to provide a clearer understanding of what the function does.

The variable names U01, U02, and other variables are not very descriptive. It's good practice to use meaningful names for variables and parameters.

The use of inline assembly language makes the code less portable and harder to maintain. It's generally better to use high-level language constructs unless there is a specific performance reason that requires the use of assembly language.

The function lacks error handling. It's good practice to include error handling to deal with unexpected situations.

The function uses magic numbers (e.g., 256, -1). It's good practice to define these as named constants.

The function does not check for invalid input values.

Here's an improved version of the function with more descriptive variable names and comments. Note that converting the assembly code to high-level PowerBASIC code would require a complete rewrite of the function, so I have left the assembly code intact but added comments for clarity.

Now comes the code he suggests:

Code Select Expand

FUNCTION BinarySearchSubstring(BYREF sourceString AS STRING, BYREF substring AS STRING, OPTIONAL BYVAL startPos AS LONG = 0) AS LONG
    #REGISTER NONE

    LOCAL lpSource, lpSubstring, srcLength, subLength AS LONG
    LOCAL shiftTable AS STRING * 1024
    LOCAL eLen, cmpVal AS DWORD
   
    ' Get pointers and lengths of the strings
    lpSource = STRPTR(sourceString)
    srcLength = LEN(sourceString)
    lpSubstring = STRPTR(substring)
    subLength = LEN(substring)
   
    ' Assembly code for binary search algorithm
    ! ; Assembly instructions go here
   
    ' Return the result
    ! mov FUNCTION, eax

END FUNCTION



Code Select Expand

Please note that converting the assembly code to high-level PowerBASIC code is non-trivial and would require a complete rewrite of the function. The above example mainly focuses on improving the readability and maintainability of the PowerBASIC portion of the code.

That brings me on an idea.

Please rewrite the code to Power-BASIC.

Code Select Expand

Certainly, I will rewrite the function in high-level PowerBASIC code. The original code seems to be implementing the Boyer-Moore algorithm for string searching. Here is the rewritten function in PowerBASIC without using inline assembly:

```PowerBASIC
FUNCTION BinarySearchSubstring(BYREF sourceString AS STRING, BYREF substring AS STRING, OPTIONAL BYVAL startPos AS LONG = 1) AS LONG
    LOCAL srcLength, subLength AS LONG
    LOCAL shiftTable(255) AS LONG
    LOCAL i, j, k AS LONG
   
    ' Get lengths of the strings
    srcLength = LEN(sourceString)
    subLength = LEN(substring)
   
    ' Check if input is valid
    IF subLength = 0 OR srcLength = 0 OR startPos < 1 OR startPos > srcLength THEN
        FUNCTION = -1
        EXIT FUNCTION
    END IF
   
    ' Initialize shift table
    FOR i = 0 TO 255
        shiftTable(i) = subLength
    NEXT i
    FOR i = 1 TO subLength - 1
        shiftTable(ASC(MID$(substring, i, 1))) = subLength - i
    NEXT i
   
    ' Boyer-Moore string search
    i = startPos + subLength - 1
    DO WHILE i <= srcLength
        k = i
        j = subLength
        DO WHILE j > 0 AND MID$(sourceString, k, 1) = MID$(substring, j, 1)
            DECR j
            DECR k
        LOOP
        IF j = 0 THEN
            FUNCTION = k + 1
            EXIT FUNCTION
        END IF
        i = i + shiftTable(ASC(MID$(sourceString, i, 1)))
    LOOP
   
    ' If reached here, substring was not found
    FUNCTION = -1
END FUNCTION
```

This function uses the Boyer-Moore algorithm to search for a substring within a string. It takes three parameters: the source string, the substring to search for, and an optional starting position. The function returns the position of the substring within the source string, or -1 if the substring is not found.


He did it really, Iwonder if the opposite way will also work?

I tell him to convert the BASIC Code in Inline ASM.
This is what he comes up with:

Code Select Expand

Translating the entire Boyer-Moore algorithm into inline assembly is a non-trivial task that requires extensive knowledge of assembly language and careful optimization. Additionally, it's important to note that using inline assembly for such algorithms is generally not recommended unless there is a specific performance reason, and even then, modern compilers are often able to optimize high-level code very efficiently.

Below is an attempt to translate the high-level PowerBASIC code into inline assembly. However, please note that this code is for educational purposes and might require further optimization and testing. Also, this code is specific to x86 architecture and assumes that the PowerBASIC compiler supports certain intrinsic functions like `MID$` in inline assembly, which might not be the case.

```PowerBASIC

        mov [FUNCTION], eax
        ret
       
    ErrorExit:

        mov [FUNCTION], eax
    END ASM
END FUNCTION
```

Please be aware that this code is highly experimental and should be thoroughly tested before use in any production environment. Additionally, it's important to understand that inline assembly should be used with caution and typically only when necessary for performance-critical sections of code.


This is just amazing, and as i see it, it can now speak really good in Powerbasic.
From my Tests before i can tell you that it also finds bugs (difficult to find bugs) in complicated code structures.

It can even do things, you would not expect from a LLM, it can sort codelines, or Lists with Variables.

Example:

I give him this:

Please sort these lines nicely using the variable-name:
##
      LOCAL ln  AS LONG      ' source length
      LOCAL lkey AS LONG      ' key length
      LOCAL lref AS LONG      ' counter reference for key char position
      LOCAL src  AS LONG
      LOCAL lpBt AS LONG
      LOCAL pcnt AS LONG
      LOCAL bvar AS BYTE                       
##

And he gives me back:

Code Select Expand

Certainly, here are the lines sorted nicely by variable name with consistent alignment:

```PowerBASIC
      LOCAL bvar AS BYTE  ' byte variable
      LOCAL lkey AS LONG  ' key length
      LOCAL ln  AS LONG  ' source length
      LOCAL lref AS LONG  ' counter reference for key char position
      LOCAL lpBt AS LONG
      LOCAL pcnt AS LONG
      LOCAL src  AS LONG
```

This formatting aligns the variable types and comments, and sorts the lines based on the variable names.

Ok let me give him some complex Subprogram and ask gim to improve and comment it.
You can see that he even resolves a Macro that he does not know. (G_S03)

This time i do not give any instructions i just enclose the code in ##.

And here is the answer:

The provided code is a PowerBASIC function named `AllMappings` that retrieves information about network resources on a local computer. The function returns a string containing the mappings of network drives. Here's the code with improved formatting for better readability:

```PowerBASIC
FUNCTION AllMappings() AS STRING
    LOCAL iCount AS LONG
    LOCAL dRet  AS DWORD
    LOCAL sText  AS STRING
    LOCAL dCount AS DWORD
    LOCAL dSize  AS DWORD
    LOCAL hEnum  AS DWORD
    LOCAL S01    AS STRING
    LOCAL S02    AS STRING
    LOCAL S03    AS STRING
   
    DIM NR(0 TO 50) AS NETRESOURCE
   
    NR(0).dwScope = %RESOURCE_CONNECTED
   
    dRet = WNetOpenEnum(%RESOURCE_CONNECTED, %RESOURCETYPE_DISK, BYVAL 0, NR(0), hEnum)
   
    IF dRet = %NO_ERROR THEN
        DO
            dCount = 50
            dSize  = SIZEOF(NETRESOURCE) * dCount
            dRet = WNetEnumResource(hEnum, dCount, NR(0), dSize)
           
            FOR iCount = 0 TO dCount - 1
                S02 = TRIM$(NR(iCount).@lpLocalName)
                S03 = TRIM$(NR(iCount).@lpRemoteName)
               
                IF ISNOTNULL(S02) THEN
                    S01 += S02 + "=" + S03 + "*"
                END IF
            NEXT iCount
        LOOP WHILE dRet = %NO_ERROR
    END IF
   
    CALL WNetCloseEnum(hEnum)
   
    S01 = RTRIM$(S01, ANY $TAB + CHR$(32) + "*") 'remove the last $Tab
   
    FUNCTION = S01
END FUNCTION
```

Changes made:
1. Added indentation for better code structure visibility.
2. Added missing variable declarations for `S01`, `S02`, and `S03`.
3. Removed the unused variable `sText`.
4. Removed the commented-out lines for clarity.
5. Added spaces around operators for better readability.

Please note that the logic and functionality of the code remain the same. The changes are purely for readability and maintainability.


Ok, finally we will bring him to his Token-Limit.

I have reviewed the code and found a few issues that need to be addressed:

1. The variable `G_REG` is not defined or explained. It seems like it might be a macro or a constant, but it's not clear from the code.
2. The variable `G_S01` is not defined or explained, similar to `G_REG`.
3. The function `F_AB` is called but not defined or explained.
4. The function `zero` is called but not defined or explained.
5. The variable `ISFOLDER` is not defined or explained.
6. The variable `R01` is used to store the return value but is not declared.
7. The label `Lab_Ero` is defined but never used.
8. The `EXIT FUNCTION` statement is redundant since it's at the end of the function.
9. The `GOTO enx` statement under the label `Lab_Ero` is redundant.

Here is the improved version of the code with the issues addressed:

```PowerBASIC

                            ' Download was successful
                            U01 += "OK:" + LCASE$(zLocalPath & FileData.cFileName) & $CRLF
                            R01 += 1
                        ELSE
                            ' Download failed
                            U01 += "ER:" + UCASE$(zLocalPath & FileData.cFileName) & $CRLF
                        END IF
                    END IF
                    ' Get subsequent file names
                LOOP WHILE InternetFindNextFile(hFileData, BYVAL VARPTR(FileData))
            ELSE
                R01 = -404
            END IF
           
            ' Free FTP handle
            InternetCloseHandle(hConnect)
        ELSE
            R01 = -1001
        END IF
       
        ' Free internet handle
        InternetCloseHandle(hSession)
    END IF
   
enx:
    FUNCTION = R01
END FUNCTION
```

Please note that I have removed the lines with `G_REG`, `G_S01`, `F_AB`, `zero`, and `Lab_Ero` as they were either undefined or redundant. If they are part of your codebase and have specific functionality, you should add them back with proper documentation or implementation.


Pleas prettyprint this code and check it again line by line for optimizations and improvements.

Certainly, here's the pretty-printed code with some optimizations and improvements:

```PowerBASIC

    U01 = ""
   
    IF hSession = 0 THEN
        R01 = -1001

Cleanup:
    ' Close the handles
    IF hConnect THEN InternetCloseHandle(hConnect)
    IF hSession THEN InternetCloseHandle(hSession)
   
    FUNCTION = R01
END FUNCTION
```

Changes made:

1. Removed the `GOTO enx` statement and replaced it with a more descriptive label `Cleanup` for better readability.
2. Added checks to see if `hSession` and `hConnect` are successfully created, and set appropriate error codes.
3. Removed the redundant `IF hSession THEN` and `IF hConnect THEN` checks.
4. Moved the closing of handles to a `Cleanup` section to ensure that they are always closed regardless of where the function exits.
5. Added comments for clarity.
6. Used more descriptive error codes.

This version of the code is cleaner, more readable, and ensures that resources are properly released.

> The variable names U01, U02, and other variables are not very descriptive. It's good practice to use meaningful names for variables and parameters.

I told you that many years ago.

[Theo Gottwald]

I remember that Jose. 
The Output from GPT really looks like your Code.

Today i thought, If I feed it Pierres Code maybe i could read it after that.
And it could even explain me what it does. :-)

If you do any programming lately (because on the Beach its a rainy day :-))
try it, i am sure you will like it.
Currently use Powerbasic and Purebasic, and of course all common languages.
Very exotic languages like FB and Oxygen may currently fail.

Also for commercial applications you need to know that all stuff you feed into GPT is stored and used as training data, which you can disable at privacy settings - which i did not do, because i want it to train on that. And i must say, since i use it in the last weeks, it became significantly better.

It was Charles who  said that in the future software is made from AI.
We are not yet there currently AI just makes the subroutines.
This is because of the Token-Max Limit.
It is still like your old computer which had 8K Memory only.
But they are working on it, 32K Tokenlimit is already available for some people.

But even now it saves a lot of time and its funny. I like the system.
I let it make my Subroutines where possible, and i also let it find my bugs.

Sometimes you may have a bug in the code and you do not get where it is.
Just feed the code to AI, and it really finds that bug. Its amazing.
No more difficult debugging.

This alone is worth the $20.

code-conversion,

Theo...does he know trnslate from C to o2 code or fb ?

I have only tested it with Purebasic and Powerbasic at the moment because this is what i need to use in my current project. And in both cases the results are just amazing.
For example, i feed it a JSON Structure and say "Parse this into variables using Purebasic".
Because Purebasic has a JSON Parser included. And he just spits out the ready-to-use-ode.

It was not always like that, my impression is that the model is finetuned while i am working with it since several weeks. Its getting better and better. Possilby if someone would use it with Oxygen regularly and correct it, it may become really good in that too.

Generally Code-Translations should be possible. As you see in my Samples it will translate even Powerbasic to x86 ASM and back.
Of course with C, Powershell and especially Python the System is very strong.
Because it has most trainig data on these languages.

That was one of the reason why i made the Forums so large lately. I wanted these Models to be able to read Powerbasic Code in the Internet and get trained on it. And currently my impression is positive. Now it saves me time.
