When I choose Run->Debug on the following program, I get a dialog saying:

Error! Debug requires RESET jump at the end of memory

I can debug the examples I've tried, but I don't see any differences from them and my program.
Using latest greatest of all software I think...

DEVICE SX28, OSC4MHZ, TURBO, STACKX, OPTIONX
FREQ 4_000_000

    It looks like you are missing Program Start. I always start with the template, and don't try to deviate from it to much.

    Thanks - I got a little overzealous deleting stuff from the template and missed that!

    If having a program start is a mandatory requirement for SX/B programs, then this sounds like an error that SX/B should check for and warn the user about. Perhaps the SX/B compiler person needs to see if there's a way to handle this situation.
      Thanks, PeterM

    Peter,
    It's not really an SX/B requirement. If you make an assembly program without "RESET label" you will get the same error.
    In this case SX/B "PROGRAM" is equivilent to assembly "RESET".
    But your point is valid, it might be nice for the compiler to "inform" the user.
    Bean.
