01 WS-TOP-RED REDEFINES WS-TOP PIC X(2).

01 WS-TOP PIC 9(1)
01 WS-TOP-RED REDEFINES WS-TOP PIC 9(2)

01 WS-TOP PIC X(2)

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/FINDBOOK?filter=COBOL

lists all the COBOL documentation. Pick your version.

depending on your version of COBOL, and compiler error settings, the redefining of a 1 byte field to 2, provides addressing, and when allowed by the compiler, will work - the next 01 is bounded based on the largest definition.
