- Subj: OPEN/CLOSE in Lahey-F77 decreases free memory.
-
- I have a large program which I must execute in DOS with 640 Kb,
- so the program is divided into 3 exe-files (400 Kb each) which
- are called from a main program. All data-exchange is done using
- external files (disk).
-
- Problem:
- Each time a file is opened/closed from within the main program
- 1-2 Kb memory less is free. When using mem /c from DOS I can see that
- it is the MAIN.EXE that increases in size. This means that data can
- only be exchanged a limited number of times.
-
- What could be wrong ???
-
- Setup: Standard IBM-486 PC, DOS 5.0, Lahey-F77L ver. 4.0
-
- Help and suggestions are appreciated. Thanks in advance ...
