    1.$ OPEN/READ INPUT_FILE   TEST.DAT
      $ READ_LOOP:
      $ READ/END_OF_FILE=NO_MORE  INPUT_FILE  DATA_LINE
         .
         .
         .
      $ GOTO READ_LOOP
      $ NO_MORE:
      $ CLOSE INPUT_FILE

      The OPEN command in this example opens the file TEST.DAT and
      assigns it the logical name of INPUT_FILE. The /END_OF_FILE
      qualifier on the READ command requests that, when the end-of-
      file (EOF) is reached, the command interpreter should transfer
      control to the line at the label NO_MORE. The CLOSE command
      closes the input file.

    2.$ @READFILE
 <Ctrl/Y>

      $ STOP
      $ SHOW LOGICAL/PROCESS
         .
         .
         .
        "INFILE" = "_DB1"
        "OUTFILE" = "_DB1"
      $ CLOSE INFILE
      $ CLOSE OUTFILE

      In this example, pressing Ctrl/Y interrupts the execution of
      the command procedure READFILE.COM. Then, the STOP command
      stops the procedure. The SHOW LOGICAL/PROCESS command displays
      the names that currently exist in the process logical name
      table. Among the names listed are the logical names INFILE
      and OUTFILE, assigned by OPEN commands in the procedure
      READFILE.COM.

      The CLOSE commands close these files and deassign the logical
      names.
