Right? 2) if this is in error who else has a complier? If this is right, who of you use it? And how slow (fast) is it compared to Fortran 77 on a VAX? 3) I have looked at the absoft fortran on the Macintosh and have found it to be 5-6 times slower than the VAX fortran because the compiler has to recompute each address in an array. The VAX knowes where in the array it was last and just increments to the next location. I imagine that this is also the case with the Amiga version of fortran. Any comments, corrections? I need an optimizing compiler for the A3000 which does at least 2 times the run time speed of the final code compared to a VAX 11/780. 4) If there is another source of fortran 77 for the Amiga please leave me a phone number. I would like to discuss your experience. If you would be willing to call me I am at (303) 980-0070. ;) thanx Jim Bowers
