Also, you can allocate memory between storage registers and program lines with the SIZE command:
XEQ (alpha)S I Z E(alpha) NNN
Where XEQ is the key to the right of the gold shift key, (alpha) is the alpha key at the extreme upper right, 'S I ' and so forth denotes spelling out the word with the alpha shifted keyboard, without spaces, and NNN are 3 numerals, spelling a number less than or equal to 319, the total number of registers on an HP-41CX.
A 41-CX will come up after a complete "MEMORY LOST" reset with SIZE = 100. That means 100 registers are allocated to data, numbered 0 - 99, and 219 are allocated to program steps. You can tell what your SIZE is on a CX, (or a C or CV with the X Functions module) with the SIZE? command:
XEQ (alpha)S I Z E ?(alpha)
That will return the current SIZE to the X register. If you haven't changed it, it should still be 100. If your programs don't need that many registers, you can choose a smaller SIZE and possibly free up enough to load the extra program.
Of course, with the card reader, you can just load whatever you CLP again later. It does eat batteries though.
