Card reader programs HP-97 to HP-41C
I have several prgrams in my HP-97 that I am trying to load into my HP-41C.

The programs load ok in the 41C but then I am unable to run them. The converted programs always start with "LABEL 97" and then they do not appear on Catalog 1. I have tried renaming the program and adding an END at the end but still can't make them work.

What am I doing wrong?

Thanks!!!

A couple of easy things to check:

- Make sure you've got at least 26 registers allocated (i.e. SIZE? should return a value of at least 26)

- Leave the card reader attached while running the program. (It contains ROM routines needed to execute some functions.)

Thank you Bob, increasing the number of registers did the trick!!!
