Works the same as RXS_nextUnqNbr except it returns a 15 byte character. It helps when creating IFS files that need to be unique by eliminating the need for the %Char Built-In Function in concatenation of variables.

Subprocedure Prototype

D RXS_nextUnqChar...
D                 pr            15a

Returns the next available number from the data area RXS/RXSUNQ as a character string.
