Element <define>

The <define> element defines special fields that will be populated and available inside a <loop> element. It is primarily used to map internal IsisScript system state variables (like current record number or total count) to accessible tags.

Each line in the argument is equivalent to the definition: <field action="define" tag="...">Isis_Variable_Name</field>

Usage​

  • Allowed content: <pft>
  • Parent elements: <do>, <function>, <hl>, <loop>, <section>, <update>

Common System Variables​

  • Isis_Current: The current record number being processed.
  • Isis_Total: The total number of records in the set.
  • Isis_Item: The current item in a list loop.

Example​

This block ensures that inside the loop, tag 1001 will contain the current MFN/Index and tag 2002 will contain the total count.

<define>
   <pft>
      '1001 Isis_Current'/
      '2002 Isis_Total'/
   </pft>
</define>
