     NAME       : DMSFSERR
     DESCRIPTION: FS Error Table Mapping Macro
     DSECT      : DMSFSERR
     NOTES      :
                  RESTRICTIONS - None
                  REGISTER CONVENTIONS - None
                  PATCH LABEL - None
                  MODULE TYPE - Macro
                  MODULE SIZE - Not applicable
                  ATTRIBUTES - Same as module
                  ENTRY-POINT - None
                  LINKAGE - None
                  Parameters - None
                  Output     - None
                  EXIT-NORMAL - None
                  EXIT-ERROR - None
                  EXECUTABLE MACROS - None

     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

                                            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.
