Run a non-DP4 program by entering the command you would normally enter at the operating system command line. Include any paths that are required to locate the program.
Use the Menu command tails to control how a program is run. For example, you might load a non-DP4 program such as a word processor with these command tails:
WORDPROC %1 %SYSTEM
The command tail %1 indicates that the filename is to be supplied at run-time, and, on MS-DOS, %SYSTEM terminates the database manager and user interface manager to increase the available memory.
Remember to use the %CLOSEDB option when running programs such as a tape backup utility, and the %BATCH option when running batch files or shell scripts
