Calling a subroutine from a subroutine

Postby dpayer » Thu Dec 08, 2011 9:22 am

Besides the issue of looping, is there a technical problem of calling subroutines from within another subroutine?

I am finding it clearer to separate out all my processes into functions or subroutines and then just call them. I find I need some of those processes within a sub routine that are part of another subroutine.

David P.:

I use GoSub within GoSub all the time ... sometimes nested 4 deep ... no problem at all.

Just make sure you don't start chasing your tail e.g.
Code: Select all
GoSub "Mary"

GoSub "John"

Nesting gosubs

Hi dpayer

I thing that the Gaev suggestion is a good one and mandatory!

More than 4 levels of nesting meke difficult to follow the program logic.

I've got some code that calls gosubs recursively without any issue.

You can call subroutines recursively ... what you need to avoid is ... a never ending loop ... like the simple example in my previous post ... something like this is fine ...
Code: Select all
If "[myCount]" ">=" "5"
   SetVar "[myCount]" "[myCount]-1"
   GoSub "Recursive"
