Trying to assemble old code it seems that the statement ORG 0x000 no long works, but has been replaced by RESET_VECTOR CODE 0x000 with the word CODE before the program. Is this true; is there a way to invoke the old style ? The templates use a form for the interrupt vector, ORG 0x004 is replaced by INT_VECTOR CODE 0x000 followed by the isr. However, this bombs when I try to assemble it; it assembles if the isr is put elsewhere and referred to with a goto label, however, in this case, the CODE designator doesn't seem to be required before the isr program. Will someone please straighten this out for me ? I was on the piclist back in 1999 and left for several years and am trying to restart.
