Non-LU6.2 Considerations for Sending Data

For non-LU6.2 conversations, specifying OUTFMHY or OUTFMHN indicates whether or not a function management header (FMH) has been added to the outbound message:

• OUTFMHY specifies that you have included an FMH at the beginning of the write buffer that should be used instead of any sysgen defaults.
• OUTFMHN specifies that no default FMH should be added to the outbound message and that you have not provided an FMH.

The CHNCONT parameter (non-LU6.2 conversations only) specifies that your task is sending a chain of outbound messages and that the current message

is not the last in the chain. Not specifying CHNCONT after it has been specified once indicates the final chain element.
