Stack underflow using sample code from Manual 3

[Andres Rodriguez]

Trying to run simulation of code copied from Manual 3, Page 18. It runs until the second For/Next ends and then I get a STACK UNDERFLOW diagnostic.

This is because the code lacks a goto main (or end) after the last for loop, so code execution falls into the subroutines directly below until the return statement is reached, where the stack underflow occurs because the subroutines weren't accessed using a gosub.

Thank you for your help. Works fine now.
