[ One of three programs received as a single package. I edited the submitter's description. -- R.D. ] 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 newsgroup, that was written using MASM 5.0 by Hardin Brothers for the April 1988 issue of PC Resource magazine, (C) Copyright 1988 by IDG Communications/Peterborough, Inc. Hardin Brothers is a freelance programmer and technical writer. Write to him at 280 N. Campus Ave., Upland, CA 91786. Enclose a self- addressed, stamped envelope for a reply.
