 FUNCTION   : This macro maps error data returned
              from SFS when issued by compatibility
              interfaces for applications. This is designed
              to enable VM service personnel to be able to
              determine the cause of an otherwise ambigous
              SFS error. This table is allocated when the
              first SFS error is encountered. DMSFSERR is
              pointed to by the FVSFSER field of FVSECT.
              DEPENDENCIES: The caller must include the
              FPERROR and WUERROR macros in his source.
              Syntax : From PL/AS module: %INCLUDE
              SYSLIB(DMSFSERR); From Assembler Module <label>
              DMSFSERR OPERATION : If DMSSFSER already
              included in current assembly, then branch to
              the end of the macro Save current status of
              PRINT pseudo-operation If 'SUP' was specified
              on the SYSPARM (ASM) or MACPARM (PL/AS)
              statement, turn off printing. Restore the PRINT
              pseudo-operation status Invoke PLAS version if
              invoked from PLAS program

                                        This will generally be 4096, but
                                        the table size may vary based on
                                        the number of entries in FVSFSSIZ
                                        which may be modified
                                        dynamically.
000C   12 Signed       4 FSEMAXEN       The maximum number of FS Error
                                        entries that can fit into the
                                        currently allocated DMSFSERR
                                        table. This value will equal the
                                        value in FVSFSSIZ, unless that
                                        field has been modified since the
                                        FS error table was allocated.
0010   16 Signed       4 FSEINUSE       The number of error entries that
                                        are currently filled in the
                                        DMSFSERR Table. This will be in
                                        the range of zero to FSEMAXEN.

                                        the position of the next
                                        available entry in the table.
                                        Note that when the DMSFSERR table
                                        is filled, the cursor wraps to
                                        address of the first entry.
