Differences like that usually point out a poor interaction between the=20 files and the make process. For example, if you provide the compiler=20 with a list of files, you may only have to load the compiler once but=20 you can compile many modules. If you use make and load the compiler=20 many times, it will take much longer to build a system.=20 We had one program that the computer center manager tried to build and=20 after 7 hours, he killed the job. It was only half way done. I=20 suggested Microsoft's Power Fortran which loaded once and compiled=20 many. The MS Fortran compiler completed the build in 2 minutes. It took=20 me around 30 minutes to figure out that it had compiled everything.=20 MS Power Fortran went on to be DEC's Fortran for PCs and I don't know=20 what it called now. CPU speeds and HD speeds were much slower when this=20 happened. Kent =2D-=20 Kent Stewart Richland, WA http://www.soyandina.com/ "I am Andean project". http://users.owt.com/kstewart/index.html
