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.

I'm sure there must be a reference that answers this question, but I'm blowed if I can find it. I want to program

SETPIN 2, DIN, PULLUP
SETPIN 5, DIN, PULLUP
SETPIN 16, DIN, PULLUP
...ETC.

I then signal branches of my program according to which pin is linked to earth, thus: IF PIN(2) = LOW THEN... (do something
ELSE... (or use CASE).

In my program I actually have several choices (a multiway switch). I am wondering if I can say something like

SETPIN 2,5,16... DIN, PULLUP

Hi
No you cannot set more than pin at a time.

You can read more than one pin at time with
PORT(start, nbr [,start, nbr]�)
(Manual page 76)

You can write to more than one pin at a time with
PORT(start, nbr [,start, nbr]�) = value
(Manual page 65)

Regards
Jman

Thanks. And I remember the TRS80 so well, and David Lien's book too!

Which mite are you using?

I would use interrupts assuming there are enough available, no problem if using a plus as all I/O lines can be setup with interrupts.

See SETPIN pin, cfg, target [,option]

Then you only need a sub(Target) for each pin.
