Search … EndSearch (procedure)

This command structure allows a series of nested commands to be repeated as long as a specific string of characters (the

search string) is found within another string (the target string). After each iteration, the target string contains all the data

between occurrences of the search string, excluding the search string. Once the loop is over, target contains the remaining

characters of the original data.

Syntax

search( target, search )

…

endsearch()

Arguments

target

Name of a variable of type string in which to perform the search.

String value to search for.
