Why can I not use subrutines in my interrupt rutine when I program in SX/B

Atle

Hi,
I'm trying to call a subrutine from my interrupt rutine but I get an error 16 UNKNOWN COMMAND.
Is it not possible to call a subrutine from the interrupt rutine, and if not, why?

I put in an example program below to illustrate the error I get.

Put the sub definition

TogglePin SUB

before the interrupt code.

Did you know that 111,111,111 multiplied by 111,111,111 equals 12345678987654321 ?

I tried to compile that, there's a GOTO Int_start that should be GOTO ISR_Start.

Oops,
Sorry about. Wasn't at a computer with the IDE.

Reminder: There's a template in the SX/B ehlp file that will help you keep everything in the right place.
