RUN command

The RUN command places an executable program in memory and starts it.


Format

     @RUN (PROGRAM) filespec /switch

     where:

     filespec       is  the  file  specification  of  any   executable
                    program.
                         Default dev:<dir> - DSK:

                         Default .typ - .EXE

     /switch        is /USE-SECTION:n
                         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.


Characteristics

     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.


Hints

     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.

                 program already in memory

Examples

     1.  Run one of your executable programs.

         @RUN TESTF1.EXE

     2.  Mount a structure  and  access  a  user's  directory  on  the
         structure.  Run one of his programs.

         @MOUNT STRUCTURE SNARK:
         Structure SNARK: mounted
         @ACCESS SNARK:<ELDRIDGE>
         Password:
         @RUN SNARK:<ELDRIDGE>FT.EXE
