leave FOR-loop prematurely (like break)

In other programming languages it is possible to use keywords like break to leave a loop. Is there a way to do this in Windev?

Hi MillesMain
i use this when reading some text file
when there is a reason to brak the loop use Finito

LOOP
IF sLine = EOT THEN BREAK
...
IF somethin g to quit the loop THEN
GOTO Finito
ELSE
do something
END

sLine = fReadLine(lv_FileID)

END
Finito:
fClose(lv_FileID)


greetings MArc.

Hi MiellesMain

Like in other langauges, the keyword in WLanguage is "BREAK"...
(See Break and Continue keywords in the help)

Cheers

Peter

Marc, thank you, but I prefer clean code, so in most cases GOTO would be a nogo, but with good naming it might be ok.

Peter, funny thing is that the search of the windev help is the worst I've seen in years. They don't show exact results on the first page sometimes, same for break. Thank you

Hi Peter, yes! Leaving a FOR-TO or a WHILE-END loop prematurely leaves the stack filled without a chance of garbage collection. Result is like a memory leak. Even in programs with the old Microsoft BASIC Compiler one could invite desaster by leaving a loop with a 'GOTO outside' command. I don't know how WLanguage reacts because I never tried to leave a loop by GOTO - I'm using BREAK all of the time, even better is a WHILE loop and exit it with a certain condition.

Kind regards,

you asked something like a break
what I show also works, thought you were looking for something other than a break

> thought you were looking for something other than a break

yeah my fault
