Recursive Function Loop-de-loop

Username_not_taken! has asked for the wisdom of the Perl Monks concerning the following question:

Hi I'm new to Perl and any advice would be greatly appreciated
I have 3 functions: FuncA, FuncB, FuncC

FuncA calls FuncB multiple times within a loop
FuncB calls FuncC multiple times within a loop
FuncC calls itself recursively

I have a global string (theString) I would like to populate through each of these functions and would like to end up with the string content as something like:

Item A          [as it goes through FuncA]
  Item B        [as it goes through FuncB]
    Item C      [as it goes through FuncC]
    Item C
  Item B
Item A
   Item B

etc

The problem I'm having is that all I get are the FuncA listings:

Item A
Item A

How do I make sure that the global string gets appended right? Thanks

I'm not entirely sure what you're asking since you didn't paste any code, but my guess is you will want to impliment some sort of stack counter. The counter will be incremented every time a function is entered and decremented ust before it returns. The stack counter can be a global (ick) or passed between the functions. Then when appending to your string you will look at the stack counter to know how many spaces to indent.	[reply]

Incase you have an adversion to exposing your code to the critique of the monks--you shouldn't be, they are mostly extremely understanding and helpful--you may find this thread of some benefit it either solving your problem or perhaps presenting your question in a better way.	[reply]

I don't get it. Please show some code. Do your 'functions' work on global variables?	[reply]
