- Presumably your INT21 handler would remember the address that it used to
- have stored, so that it could pass non-linked file calls on to DOS.
- Just use the old INT21 handler to handle your link calls.
-
- I would love to see a good symlink handler for DOS. I saw one once that
- seemed to work, but it did not support the DOS EXEC call, so I could not
- use it to symlink program files to each other. This would have been
- perfect for the PBMPLUS tools.
-
- One question: How do you propose to be able to tell the difference
- between a symlink file and a real file that happens to contain a
- pathname?
