Okay, so I've been doing COBOL too long... 8^) Yes, in BASIC it's STEP.
Same idea as COBOL's BY option. (In COBOL it would be PERFORM VARYING
variable BY inc FROM start UNTIL variable IS GREATER THAN end (I think --
it's not a common usage of the Perform verb.))
and while loops (I rarely use for's), but C really
suffers from a lack of
a general error trapping mechanism that one can invoke to break out of
loops as required. Sometimes I think goto's are the answer but I can
never find an appropriate way to implement it.
errflag := 0 /* is it := in C to assign a value? */
DO WHILE variable < end AND errflag = 0 {
do stuff
variable++ /* I think that increments a variable */
IF error THEN
errflag := 1
ENDIF
LOOP
IF errflag = 1 THEN
do error processing
ENDIF
No, I'm not a C programmer (nor do I play one on TV).
