## Comments:

      This command is interesting if you have problems with crashing programs.
      With the command you can see if there is enough memory to execute the
      program. If the lower memory is too small it may help to load the
      program into high memory with the LH / LOADHIGH command.
      MEM supports NLS (national language support).
