STATUS 

USING STATUS 

The value of status can be tested as a whole, or the two characters can
be tested separately as status-key-1 and status-key-2.  In any case, the
status of each call should be tested immediately following execution of
the call.  Unless the first character of status = "0", the call was not
successful.

For example, a sample status parameter definition might be:

          WORKING-STORAGE SECTION.
          .
          .
          .
          01 STAT.
             02 STATUS-KEY-1 PIC X.
             02 STATUS-KEY-2 PIC X.

These items can then be referenced in the PROCEDURE DIVISION. For
example:  to test only the first character:

        IF STATUS-KEY-1 NOT = "0" THEN
            GO TO "ERROR-ROUTINE".

To test the entire status word:

        IF STAT = "23" THEN
             DISPLAY "RECORD NOT FOUND".

Note that the word STATUS is reserved.
