RE: hp41cx named variables in extended memory
Making a simple arithmetic:

20 regs in HP-41 memory = 7bytes * 20 = 140 bytes

My routines use, for the same 20 regs : 499 bytes or 263 bytes (and more X-Memory to hold the registers).

If you see just the bytes, no way to win this war. But the main idea is to have private numbered registers for those programs that serve as basis for others.

Both routines make the x-file the current one only at initialization. So, if your programs make use of others X-files, you will need to make the X-Reg file the current one again.

Best wishes!
