SDF-I

The SDF-I utility routine merges group or system syntax files and performs consistency checks. The syntax files to be merged may be files supplied by Fujitsu and/or created by the user (with SDF-A). Syntax files merged with SDF-I can also be unmerged using the same program. SDF-I supports syntax files with or without a PAM key.

Installation is normally performed using the installation monitor IMON. Since IMON does not merge the SUSFs (software unit syntax files), but activates them as the basic system syntax file and subsystem syntax files instead, SDF-I is only used now in special cases (e.g. when merging subsystem syntax files or group syntax files created by the customer or when displaying syntax file information.
