True, and all too common in single-file RPL programs. However, the best practice for writing RPL, demonstrated beautifully by D. R. Mackenroth (of HP) in his book HP48 Programming Examples is to create a separate directory for each program, consisting of a main program that calls several small subprograms (similar to sound Forth practice). Mackenroth gives a simple example of computing the hypotenuse of a triangle where the main program <<GetA GetB ComputeH Label>> is just a series of subprograms (verbs) that employ minimal stack juggling. Nice and readable!

This is the technique I try to employ when I need to write anything significant in RPL. Also use plenty of local variables. Whether or not that kind of design is appropriate for a handheld calculator is certainly up for debate, however.
