/CREF IS A CROSS REFERENCING PROGRAM FOR THE OS/8 ASSEMBLERS,
/PAL8 AND SABR. THE PURPOSE OF CREF IS:

/ 1) PROVIDE A SEQUENCE NUMBERED (DECIMAL) OUTPUT LISTING

/ 2) PROVIDE A LIST OF ALL USER DEFINED SYMBOLS AND LITERALS
/   AND THE SEQUENCE NUMBER OF THE LINES IN WHICH THEY OCCUR

/FIXES FOR MAINTENANCE RELEASE:
