msx_parms_parser - parser.com

A Z80 Assembly function to parse MSX-DOS command line parameters and execute the corresponding code.

How to use:

1. Define you options in the parms_table
2. Add your data / flags requirements in table data_option_
3. Each option must have a "dw nnnn" entry, which is a label to the routine that will implement the logic for that option
4. Code the routine for that optin, as a regular sub-routine, terminating with "ret"
5. If that routine is self-contained and don't need any further processing, add this code before the "ret" instruction: "xor a; ld (ignorerc),a"
6. Inside a routine for each argument, you can establish the order of processing as you wish. For example, in the /file routine, you can check if the another mandatory option was passed, as for example: "/e" to encode or "d" to decode -> these needs a flag set in the table data_option_. If the value is $ff than the parameters was not passed.
