Syntax

position=RXMATCH (rx, string)

Arguments

position: specifies a numeric position in a string where the substring that is matched by the pattern begins. If there is no match, the result is zero.
rx: specifies a numeric value that is returned from the RXPARSE function.
string: specifies the character expression to be searched.

Details

RXMATCH searches the variable string for the pattern from RXPARSE and returns the position of the start of the string.

Comparisons

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.

Example

See the RXPARSE function Example.
