However, my code tends to do a lot of Agreed, but I think there is more than C, so for example instructions like ABCD, NBCD and SBCD which are not used by C seem very handy when using COBOL. I guess for some other instructions this holds also (not necessarily COBOL, but for FORTRAN etc). At least I always though that CISC does not mean: C Instruction Set Computer :-) >structure accesses with pointers such as "pointer->field". The >68020 double-indirect-with-offset addressing mode is a real life saver [...] Again agreed. -- Dolf Grunbauer Tel: +31 55 433233 Internet dolf@idca.tds.philips.nl Philips Telecommunication and Data Systems UUCP ....!mcvax!philapd!dolf Dept.
