Can you set that file hidden, so the other apps can't even see it? Or check
the archive setting? Or change the extension or the name? Or set it
read-only? Dos is limited in this stuff.
The following is NOT code, obviously:
1) i want file test.txt
2a) change it's name to test_inuse_by_code1.txt
2b) if the app is #2, it's test_inuse_by_code2.txt
2c) or set the other semaphores as bit tests in the name: test_bits.txt
2d) or a separate file of attributes, test_atts.txt contains them.
3) use the file
4) change the name back when done.
