OxygenBasic Examples / Re: Msgbox asm

Last post by Charles Pegge - Today at 09:16:57 PM

Here's a trade secret:

You can reveal the Assembly code of any piece of Oxygen by using the #show command:

it shows the intermediate code followed by Asm code

Code Select Expand

int a,b,c
#show {
a=b+c
mbox str(a)
}

The code can also be stored directly into a text file:

Code Select Expand

int a,b,c
#show  "t.txt" {
a=b+c
mbox str(a)
}

Hi Charles again..

How I can add correct two numbers in 64 Bit Mode in this msgbox example?  Thx in advance , Frank

Code Select Expand

' 64 bit x86
'
$ FileName "test64add2number.exe"
#include "$\inc\RTL64.inc"

byte val1
byte val2
int result
   
    val1=4
    val2=6 '

     '' mov eax,val1 
     '' mov eax,val2  ''multiply eax by ebx  "
     '' mul val1 'ebx 
     '' mov result,eax


'------------------ //
     mov rax,rdi
     add rax, val2 
     'add val1 'rax,
     mov rdi,val1
     mov result,rax
'------------------ //

zstring tit[]="64Bit OxygenBasic"
zstring msg[]="Hello dear Animal World! " + str(result)

'' oxygen 64 bit
''
sub  rsp,40h
mov  r9,  0       
lea  r8,  tit   
lea  rdx, msg   
mov  rcx, 0
call messagebox       
add  rsp, 40h

Hi Frank,

I could not make sense of your example but in any case, you will need to specify the allocated char count of the zstring

type aStruct
    a as long
    b[16] as zstring
end type

Here is a little sizeof example

Code Select Expand

Print SizeOf(Byte) ' returns 1

Type mybar
    a As Integer '4
    b as float '4
    c as long '4
    d As Double '8
    e as ulong '4
    f as short '2
    g as byte '1
End Type

dim myfoo as mybar
print SizeOf(myfoo) ' returns 32

OxygenBasic Examples / Type question

Last post by Frank Brübach - Today at 03:24:03 PM

Hello Charles,

Can I add a value and a String with a Type in a function?

Code Select Expand

type aStruct
    a as long
    b as zstring
end type

function one_add(long a,b) as long
dim st as aStruct

st.a = 5
st.b = "Thor"
return a+b

end function

function two_add(long a,b) as long
dim st as aStruct

st.a = 5
st.b = "Thor"
return st.a+str(st.b)

end function

print "one_add: " + one_add(2,4) ' result 6
print "two_add: " + two_add(2,4) ' result 50 ' ???

some signed byte values:

0x7f -->  127
0x80 --> -128
0x81 --> -127
...
0xfe --> -2
0xff --> -1

0x104 modulo 0xff --> 4
