[Zlatko Vid]

Hello Charles..others

does o2 support

Do
...
...
...
Loop While expr

?
I mean i always use Do / End Do
or
While / Wend

or can i replace

Do /Loop While with...

Do loop ? and how  ?

Yes,

Code Select Expand

uses console
int i
do
  i++
  print i cr
'OPTIONS:
'loop while i<10
'loop when i<10
'loop until i>9
'loop if i<10
loop if not i>9
wait

Similar option exist for exit and continue

or can i use just this :

Code Select Expand

int i
do
  i++
  print i cr
   if i=10 : exit do : end if
end do

Hi Aurel,
While waiting for Charles answer,
on my side, one thing I like is to be able to
put dual conditions, one in the do line and also one in the loop line.
This make the code more compact and often easier to read.

// KickEnd

include once "windows\msvcrt.inc"

! BCryptGenRandom lib "bcrypt.dll"(sys hAlgorithm, sys pbBuffer, dword cbBuffer, dword dwFlags) as long

SetConsoleTitle("loop")
long index = 0
byte RandomByte

printl
printl "do until RandomByte > 245"

do until RandomByte > 245
  BCryptGenRandom(0, @RandomByte, 1, %BCRYPT_USE_SYSTEM_PREFERRED_RNG)
  printl "  index = " index ", RandomByte = " RandomByte
  index ++
loop while index <= 5

printl "loop while index <= 5"
printl
printl : printl "Press a key or click to end"
waitkey

end

The compiler has to break all these looping expressions into a simple  do .. loop  containing one or more conditionals, containing an exit/continue instruction.

They are all luxury items for hand-coding. If you use an AI agent to produce the code, you might find it simpler to eliminate all while and for constructs.

Hi Pierre....Charles

my intention is to avoid Loop While in this loop construct
because really i don't use in any of my programs Do/Loop While
i prefer Do/End Do and While/Wend

in first place i was asking because this is used in many C or Java programs
and i am doing some translation
