Handling SDF standard statements and domains

The SDF standard statements are contained in the SDF syntax file. A separate SUSF is supplied for SDF.

SDF-I merges the standard statements when the syntax file for SDF is to be merged. The standard statements are then available to all the programs in the output syntax file. If a given SUSF is merged into a syntax file that already includes the SDF syntax file, the programs in the newly included syntax file also have access to the standard statements.

All application domains from the input syntax files are merged into the list of application domains of the output syntax file. Domains to which no commands belong are not removed by SDF-I. If desired, you can remove the redundant domain by using the SDF-A/SDF-U statement REMOVE.
