Frees memory allocated by other regular expression (RX) functions and CALL routines
Category: Character String Matching
Restriction: Use with the RXPARSE function
CALL RXFREE ( rx );
rx
specifies a numeric value that is returned from the RXPARSE function.
The regular expression (RX) functions and CALL routines work together to manipulate strings that match patterns. Use the RXPARSE function to parse a pattern you specify. Use the RXMATCH function and the CALL RXCHANGE and CALL RXSUBSTR routines to match or modify your data. Use the CALL RXFREE routine to free allocated space.
See the RXPARSE function 'Examples' on page 811.
