FOR

FOR [ target := init ] TO cond STEP step // commands END

Excecute the commands in the FOR loop while the condition holds true.

target

The incremental counter variable to initialize with the value init (e.g. #i).

init

The value with which to initialize the counter variable target (e.g. 0).

cond

The condition which should be tested at the start of each loop (e.g. $#i < 10). See the condition topic for the condition syntax.

step

The incremental value to add to the counter variable target at the end of each loop. The assignment syntax (e.g. #i := int $#i+1) is allowed.

FOR #i := 0 TO $#i < 10 STEP #i := int $#i+1
        BUTIL MSGBOX MSG; #i = $#i
END
// an example without initialisation
FOR TO $#x > $#y STEP #i := int $#i + 1
   // do something here ...
END
