foreach ($a, $b, $c)...

[Ken Sington]

has anyone tried:

foreach ($a, $b, $c){
...
}

well, it doesn't work.

but what if I wanted to do that?

It does work just fine, as long as your replace '...' with some valid
perl syntax.

"It doesn't work" isn't a useful problem description, especially when it
does in fact "work".

but what if I wanted to do that?

Then you do it.

My, what a specific description of the problem. It "works" fine for me,
assuming the variables had already been defined.

Dude, what does "doesn't work" MEAN? Provide an EXAMPLE. It DOES work
if you do it right:

$ perl -e '$a = "This"; $b = "DOES"; $c = "work!"; for ($a, $b, $c) {
print "$_ \n" }'
This
DOES
work!

You are the only person who knows what "doesn't work" means when
you say it.

One or more other people must know what you mean when you say it
if they are to be able to help you understand, fix or change it...

I'm sure many people have

foreach ($a, $b, $c){
...
}

well, it doesn't work.

Please define "doesn't work".
- What did you expect it to do?
- What actual behaviour did you observe?
- In which way was the observed behaviour different from the expected
behaviour?

but what if I wanted to do that?

Please define "that". What did you expect this code fragment to do?

folks are too kind.
yeah, i read the guide lines.

I thought I was asking the right q. guess not.

well, the problem was solved.
I was just playing around with foreach loops.

but thanks folks.

great hobby, that PERL.

KS> I thought I was asking the right q. guess not.

you asked the right question but with too little information. do you see
the difference? and as many have said, the phrase 'doesn't work' all by
itself is useless and carries no information. context is all.

KS> well, the problem was solved.
KS> I was just playing around with foreach loops.

and you never showed what the real problem was nor your 'solution'

KS> but thanks folks.

KS> great hobby, that PERL.

then pick up another hobby like juggling swiss army chainsaws. if you
want help and are asked for more information, you are supposed to give
it.
