• The WEB_MAP statement allows you to specify which incoming and outgoing fields the WebRoutine maps between the web page and the WebRoutine. The WEB_MAP statement's FOR() selector specifies whether the fields are mapped as an incoming (*INPUT), outgoing (*OUTPUT), or both (*BOTH).
• Only fields in a WEB_MAP statement with a FOR(*OUTPUT) or FOR(*BOTH) can be placed on the web page.
