2. Considerations for using RUN/EXEC to execute DOS programs ============================================================ RUN and EXEC may be used to execute DOS programs and batch files, as well as Windows programs. When running a DOS program, several things must be considered. If the DOS program is run directly, Windows will use the "_DEFAULT.PIF" PIF file to control the DOS session in which the DOS program will run. Alternatively, the name of a PIF file may be executed. A custom PIF file may be created with the "PIF Editor" application in Windows. The PIF file can specify the name of the program to run, command line parameters, working directory, and a variety of options. Three options in particular should be set correctly in order to minimize potential problems: The program should be set to run in a window (rather than full-screen), the program should be allowed to execute in background, and the program should not execute in "exclusive" mode. If these three options are set differently, it is possible that the program will be suspended by Windows, and will not run to completion without user intervention.
