[BUG] Stack Pollution by PPL PRINT Statement

[John R. Graham]

Still experimenting with PPL, trying to get the feel of it before porting any of my apps from the 50g. I encountered this:

Code:

EXPORT CHARLIE()
BEGIN
  PRINT("Entry mode is "+Entry);
END;

When run, this displays, as you might expect:

Code:

Entry mode is 2

on a separate scrolling screen (I'm an RPN junkie). What was unexpected was that the same text ended up on the lowest level of the stack as a quoted string. A little more experimentation revealed that this behavior only manifests with PPL programs that do not return a value.
