There is no built-in command, however the HELP LEX file will produce a list of all keywords in the machine, which includes built-in OS commands, LEX files and ROMs. To find out which keywords there are in a new ROM (or EPROM, or new LEX file), do this: 1. Install the HELP LEX file 2. Type HELP [RTN] 3. Capture the output (print hard copy or capture log using IL-Per or pyILPer witht he PIL-Box). Note: the output is many pages long, even for an empty HP-75. 4. Power-off, Install the new ROM (or EPROM or LEX file), power-on 5. Type HELP [RTN] again 6. Capture this 2nd output 7. Compare the output lists It can be tedious if you are comparing printed copies, but is easy if you are using the PIL-Box as you can use a text editor to compare the files and highlight the differences. Also, the HELP command output describes the argument types for each keyword, so could help you to figure out what they do. See this article about the HELP LEX file (Message #7), with examples and links: http://www.hpmuseum.org/cgi-sys/cgiwrap/...read=76286 --Bob Prosperi |
