>>Anyway, I keep getting ProDOS error $56. This is not defined in >In other words, the 'address of file buffer' in an OPEN, GET_BUF or SET_BUF >MLI call is in conflict with the Systems Global Page memory bit map. That's one possibility. I have had first hand experience with another under PRODOS 8. I received this error (pretty sure this one) when my file buffer address was not page-aligned. I was not sure whether it needed to be when I started playing with PRODOS MLI calls. Passing a page-aligned address (i.e. the low order byte of the address is zero) corrected the problem.
