BYTES on the compiled program returns 75 #48F7h.

Aha! "Z5_" does NOT mean BINT5. It means ZINT 5, which I could only discover by downloading the copy from Eric's site and disassembling it. The built-in assembler does not know what "Z5_" means, and neither did I.

Suggestion: Use HP 50g ASM notation, and include the checksum (which is #FB66h for the above program), when posting System RPL source code. Thanks in advance!

By the way, Gerald, I really like the algorithm used here: Convert to base 5, then double that number as a base-10 number. Very cool!
