TOPS-20 Commands Reference Manual
Places an executable program in memory and starts it.
@RUN (PROGRAM) filespec /switch
is the file specification of any executable program.
Default dev:<dir> - DSK:
Default .typ - .EXE
specifies the memory section (from 0 to 37 octal) in which your program is to run. You can use this switch only if your program can be contained in one section.
Efficiency of RUN
The RUN command does the work of the pair of commands GET and START. It is a faster and less expensive means of executing programs than EXECUTE, or than LOAD and START. Therefore you should store frequently-run programs in .EXE files and run them with this command.
Alternative to RUN command
When you type only a program name, the system looks for a matching system program. When you precede the program name with the RUN command, the system looks for the program in your connected directory. The RUN command can be eliminated by typing the directory name with the program name. These two commands for example, each run SORTER located in the connected directory:
@RUN SORTER.EXE @<SMITH>SORTER.EXE
Effect on Memory and Terminal
The RUN command clears any unkept forks, places the specified program in memory, starts it and leaves your terminal at command level in the program (if any), or at TOPS-20 command level.
