Ah I see... intriguing idea :) Rereading your original post it should have been quite clear what you wanted. Unfortunately (as far as I know) Mario is right, there doesn't seem to be a clean solution other than manipulating the return stack. I've (...)

This feels vaguely similar to a question just recently posed, almost. I need a way to get out of a user program that intentionally defines an infinite loop. My best attempt so far at an exit word : exit POWER_OFF LCD_4TH LCD_REFRESH ; in the context (...) (22 years ago, 16-Jul-02, to lugnet.robotics.rcx.pbforth)

Hi Matt, I'll try to help. :o) First, you have to specify the type of sensor that is hooked on the port. You do that with: type port SENSOR_TYPE Let me know if you need to know the different values for 'type'. 3 is a light sensor. Ports are numbered (...)

Hi, (...) My questions were a bit ambiguous. I don't want to abort the routine running on the ISR; I want (from the ISR routine) to abort a currently running user routine - eg abort something started from the console. So, for example, if a program (...) (22 years ago, 15-Jul-02, to lugnet.robotics.rcx.pbforth)
