Making a chart of GSB/XEQ/GTO/LBL/RTN functionality and quirks

[Dave Britten]

Thanks, there's some great ideas there I hadn't thought of.

This is what I've got so far: (I still need to get all the details for the 33S and 35S)

This is purely meant to cover the nuances of flow control - LBL, GTO, GSB/XEQ, RTN - not any other functions like tests or loop control functions. Handy when porting a program from one calculator to another and you need a quick reference to see if differences in the max subroutine depth, or the behavior when executing past the end of the program will need to be accounted for, for example.

I'm making the bold assumption that the 25 and 25C, 29C and 19C, and 67 and 97 are identical pairs. If anybody can point out areas where they differ in one of these regards, I'll split them up or add an extra note.

Also, I'm not sure if there's enough surviving information on the 95C to fill out all of this, but I might give it a shot.
