I appreciate the responses I got on referencing Apple i/o slots from Pascal. It seems that the method of choice is to use a variant (aka TRIX) record which can be an integer (for the slot address) and a pointer (to reference the slot). There are two excellent articles, with programs, in BYTE magazine: Feb. 1981 and July 1981. Both resort to assembler, but the second article uses much less than the first. Ned Danieley duke!ndd
