call stack question

[Tom Kuurstra]

Hi people,

I could really use some help with the following.

Consider the following code:

----

sub a
call sub c
end sub

sub b
call sub c
end sub

sub c
do stuff
end sub

----

Now i need to know in sub c which sub (a or b) made the call to sub c.
I can do this using passed parameters or a global var construction
but i was hoping that PB has some way to tell me which sub made the call.
Anybody have any ideas? Thanks!

Regards,

Tom

Without passing a parameter?

The only way is to set up a SHARED variable something like CurrentProcedure$ which you must set at each entry and restore on each return

Other than that, forget it.

Better still, why not use use a parameter?

I know it's just one man's opinion, but I think PB/DOS is stable enough now to support passing parameters.

I think it's everybody's opinion that PB/DOS has alweys been stable enough to support passing parameters and way more. Tom has likely his good reasons to try other ways, impossible to tell without knowing the context.

I have indeed good reasons to wanna do it the way i asked, but it looks like
that's not possible. I've already implemented a global var construction.
I must say however that this is kinda lame. When debugging you can check
the gosub/call stack, so why can't i access that from PB to see what subs
have been called? Ah well, global vars are good for everything i guess...
Thanks for the help though.

Tom
