 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Apologies, despite my best efforts I've been thinking about this: 1. A mechanism to identify a custom shell program; either an OPTION or a named file in a fixed location, e.g. a file called SHELL.BAS in the root. 2. A program that exits via END or Ctrl-C automatically executes the shell program when it returns to the BASIC command line. 3. An alternative to Ctrl-C, e.g. Ctrl-X which returns to the BASIC command line and does not execute any shell program. 4. An extension to the END keyword that mean exit to BASIC without executing the shell program. 5. An extension to ON ERROR to allow a program to control whether it should exit to BASIC or execute the shell program - in the latter case MM.ERRNO and MM.ERRMSG$ would ideally be written to a file in a known location, e.g. a file called ERROR in the root, or somehow passed in on the MM.CMDLINE$ of the shell program. I don't suppose there is any possibility of this in the future ? Tom Edited 2020-10-16 22:02 by thwill MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

I assume this is a joke and will treat it as such |
