Is there a lot of difference between ATT 3B2 "f77" and the ATT FORTRAN-XLTP, their compiler that uses the floating point co-processor. Basically, is there a lot of work to port a fortran program written for f77 to that for FORTRAN-XLTP. We are interested in porting a spice program. Thanks. T. Y.

We have something call FORTRAN-XLA (It's probably the thing your interested in.) Yes, it appears to be f77 in disguise. Same error messages, same libraries. We did, in fact, port SPICE 2G to it successfully, however, there are a couple of bugs in the compiler, most notable (the one that caused the most trouble), was a function call in a 3-way IF statement: IF(FUNCX)10,20,30 This caused 2 evaluations of FUNCX(), which can cause trouble, if your FUNCX routines does input, for example, or changes variables... Otherwise it worked fine. john@polygraf.bitnet john@polyof.poly.edu
