Hex -> Dec for the HP-41C/CV/CX

This program is free and was created and uploaded by Russ Gilbert.

This program is supplied without representation or warranty of any kind.

Filename 41hexdec.raw. XEQ 'HD'.
There are two notices when the program begins, '0-9 DO R/S' and 'DO J TO END'. The letters A-F just press those and wait a few seconds. For 0-9, you have to hit R/S after pressing them. When you are finished with the hex number, hit the J key and the decimal number will be displayed. The original hex number can be seen using the ALPHA key. Requires SIZE 030. Too big to fit in stock 41C with SIZE 030. Doesn't require CX extended funtions.
