Hello everyone.
I wanted to ask if there is a possibility in mmbasic to pass variables or flags directly to a program at its launch.
I try to explain myself better, but with my English it will be difficult.
for example, given the program test.bas, is it possible to pass flags "load test -g" directly?
If not, is the only system to create an external file to read after booting?
Thank you all.

Ciao PCG

Are you able to store them in a file on disk?

ie. when test.bas starts, it looks for a file called test.cfg if found, it opens it and reads lines from the file - and this will be it's config data. Fred.bas could look for a fred.cfg and so on

You'll probably need to have either some parsing method or go for a strictly formatted file where line1 is x and line 2 is y etc...

Thanks for the reply CaptainBoing.
Now I write the data in a text file on the SD that is read by the second program once launched and it works.
I wanted to see if a better system existed and how You do in these cases.
Possible to use switches like in the dos? (es.. deltree /Y).
Thanks again.

The original Maximites had
MM.CMDLINE$
Just what you are looking for.

Jim

Edit
I think it's still there in the DOS and Pi versions.
Not so sure about the others.Edited by TassyJim 2019-02-15

Hello everyone.
Thanks Jim.
Yes MM.CMDLINE$ It's OK, but I think it was dropped in the micromite
versions as well as the maximite merge file$.
I confess I have not read all three manuals carefully, I will check better.
Now I'm sketching the code with the mmbasic dos version, but it will have to run on the H7 arm I'm finishing.
I have seen MM.PERSIST "Sets a user variable that will survive restarts and watchdog timeouts" so I think resident in flash, to be used sparingly.
In short, it is the eternal dilemma of a new platform, what to keep and what to innovate ..
