- There are two parts that affect the open files. One is on DOS side.
- You can increase this part by changing the "FILES=" line in
- CONFIG.SYS. The second part is on MS FORTRAN side. According to MS
- FORTRAN 4.1 & 5.0, some assembly code must be changed to increase the
- limit. Sorry I never use MS FORTRAN 5.1. Under DOS, I ever increased
- the open files to 40+. I cannot open more files under DOS. But under
- OS/2 1.0, I can increase the open files to 60+. Because this was what
- I need at that time, I don't know the limit. Again, this is for MS
- FORTRAN 5.0, not 5.1. But I don't think the number of the open files
- will decrease.
