Substrings are stored in either the string or numeric array defined in the assignment statement. The array will be re-dimensioned to the exact size to store all of the substrings. Unlike ExPLODE, EXPLODEX allows ignoring specific variations (case sentive, spelling etc), see example below ”[Aa][Nn][Dd]”.

By default the nature of regular expressions is “greedy”. This behaviour can be changed using the <a href="en_regexminimal.html" class="wikilink1" title="en:regexminimal">RegexMinimal</a> statement.
