#### Example 1
```rpgle
      *--------------------------------------------------------------
      * This example code retrieves the composition engine buffer and stores it in the field gXmlRequest.
      *  This process might be used when calling a web service.

     H DFTACTGRP(*NO) BNDDIR('RXSBND') ACTGRP(*CALLER)

      /copy QRPGLECPY,RXSCB

     D gXmlRequest     S                   Like(RXS_Var64Kv_t)
      /free 
       gXmlRequest = RXS_GetComposeBuffer();

       *INLR = *ON;
      /end-free
