The IOA Online facility can be activated under the VTAM environment, and is therefore available for KOA processing.
Note: The IOA Online facility is also available under various online communication systems (for example, CICS, IMS/DC, TSO). Therefore, KOA scripts can access the IOA Online environment directly through these facilities.
Since KOA is basically an extension of KSL, every KSL script (with minor modifications) can be run as a KOA script. This is achieved by including a few communication commands in the script, as in the sample script (member RUKORDER in IOA SAMPLE library) shown below:
