STOP Statement 

The STOP statement provides a means of temporarily suspending execution
of your object program, as well as a means of stopping it completely.

Parameters 

RUN                   if specified, causes the entire run-unit to cease
                      execution when it is encountered, regardless of
                      whether the STOP RUN statement is in a subprogram
                      or a main program.  Control is then returned to the
                      operating system.

literal-1             may be numeric, nonnumeric, or any figurative
                      constant except ALL. If the literal is numeric, it
                      must be an integer.  Use of a literal in a STOP
                      statement temporarily suspends the object program.

                      The literal variation of the STOP statement is an
                      obsolete feature of the 1985 ANSI COBOL standard.

Description 

If the STOP RUN statement is used in a consecutive sequence of imperative
statements within a sentence, it must appear as the last statement in
this sequence.

If STOP literal is used, the object program suspends and the literal is
displayed at the operator's console.  A system generated message is then
displayed, followed by the message TYPE GO TO RESUME. 

When the operator responds with "GO", program execution resumes with the
next executable statement following the STOP literal statement.  For
example:

     STOP "MOUNT TAPE COBTEST"
     OPEN INPUT COBTEST.

The STOP statement above is to instruct the operator to mount a magnetic
tape to be used as an input file for the program.  After the operator
mounts the tape and makes appropriate console responses, the program
resumes execution when the word "GO" is typed in.
