The entry was ok for the checksum, the first use display some info then 'memory lost'

Sorry to hear that, but I just verified that the hex listing there is correct, so that's not what caused your crash. I strongly suspect that your copy of the MAKELEX program (in your HP-71) contained an error. Did you save MAKELEX on cards or print a listing from your '71? If so, please compare it character by character with the listing in the book.
