INF: How to Use Variable Length Recordsets with COMTI (297868)

SUMMARY

When data of variable length with field type of recordset is sent to the host by way of COM Transaction Integrator (COMTI), COMTI sends the final field to the host padded with NULL characters (0x00) up to the defined maximum size of the field.

When the last parameter in the type library is a recordset that refers to an OCCURS DEPENDING ON value, the null values will be passed to the mainframe unless the option Final field from host is variably sized (Return Value) is selected.

The Final field from host is variably sized (Return Value) option is located in the method's Properties on the Advanced tab.

MORE INFORMATION

The following trace snippet from an SNA Server Logical Unit (LU) 6.2 message trace shows the problem when the Final field from host is variably sized (Return Value) option is not selected:
