- Summary: switch.arc, demonstrates how to read command line switches
- Approved: dhesi@bsu-cs.UUCP
-
- SWITCH demonstrates one way to read single-letter switches from the
- command line. The command line switches are received by the program
- from the program segment prefix (PSP) beginning at offset 80h. The
- executable and assembly source are supplied.
-
- The program uses a single memory word (one bit per switch) to store
- information for 16 switches, assumed to be /A through /P. All switches
- are treated as toggles. The code commenting, wording of printing
- messages and some of the code itself have been changed in a number of
- places.

- This is one of three programs, being posted consecutively to this
