I'd like to see static variables in procedures.

Procedure.l Change()
static a.l = 5
a = a + 1
ProcedureReturn a
EndProcedure

result.l = Change()
PrintNumberN(result)
result.l = Change()
PrintNumberN(result)

should print 5 and 6

This way you could remember some state without using global variables.

Even more nice would be to have static vars that have visibilty scope in exactly the source file where they are defined (even if included?). Would give us some object oriented feeling without much burden.

yes, i miss using static vars inside functions

Yes, we have Global, Shared and Pretected, so all we're missing is Static. These really come in handy for procedures that are called frequently, like once per loop to process some music, etc, without having to use dozens of Global variables.

Holger,

I agree with you about the need for static variables, but shouldn't your example print 6 and 7, not 5 and 6?

Actually, I think it would print 6 and 6, since a is set to 5 each time and then incremented by one. There would have to be some switch put in there that would check to see if it had already been defined I guess. Unless Static assigns an initial value to a the first time through (5) and then ignores the 'Static x = x' line on subsequent times through. If that's the case, and actually I think it is, then the results would indeed be 5 and 6. (In Powerbasic, Static allows you to set it's type , but not it's value on the same line: 'Static x AS INTEGER').

That's how it works in C.

No, it really would be 6 and 7. It's set to 5 and gets increased before it gets printed.

You're right on this one, Tinman. I realized it right after I posted it, but found no way to edit once it was there . (Should have used Preview instead...).

You should be able to edit your posts by clicking on the icon that looks like a pencil over a piece of paper at the top of your post. You need to be logged in before you look at the page which contains your post or the icon won't show up.

Ah, works now! In the past, I've had problems with the forum where I'd log in, and then after I read a post, I'd have to re-log in every time (it wouldn't remember that I was logged in already), so I'd just manually log in after clicking on "Reply to Topic". This is much better
