RE: [UV] Recursive GOSUB

[Glenn Herbert]

This is an interesting topic as this concept within BASIC was actually 
developed and tested with great success here, though unfortunately never 
implemented for field release.  I don't quite recall now how the 
implementation was done, but I believe there was a new statement used to 
indicate that an internal subroutine was either global or local and that 
would determine how variables were treated.  I don't believe it was that 
difficult to implement either...

Anyways, it sure would be a nice feature in the real world!

At the risk of sounding like an ad, there's an article at
http://www.precisonline.com/inner.html discussing the concept of "inner
recursion", that is, recursing inside of a single program.
