Richie: The sample of code in your message is perfectly legal. Type coersion has virtually no limitations placed on it in Modula-2. In most cases all that happens is that either high-bits are truncated or zero-extended depending on if you are going smaller to larger or vice-versa. One possible reason for the problem in porting from the VAX is that BM-2 defines ADDRESS as POINTER TO BYTE, where as your VAX compiler probably defines it as POINTER TO WORD (with WORD being 32-bits, probably). So on the VAX this picks up a 32-bit pointer value on the Amiga it only gets the first 8-bits of the pointer, which is probably why the system crashed later as you mentioned. >> Leon Frenkel <<
