SDF-A (System Dialog Facility-Administration) is a software product for administration and modification of the BS2000 user interface, which is implemented using SDF.
SDF (System Dialog Facility) requires, for the internal processing of inputs, syntax descriptions; these are kept in special files, called syntax files. These syntax files can be arranged in a hierarchical structure with a maximum of three levels (see "File hierarchy").
The specification of the user interface simultaneously defines the scope of the system. By modifying the user interface, it is therefore possible, for example, to provide specific users with additional privileges or to restrict the rights and authority granted to certain users. SDF-A can be used to process the user interface accordingly.
This manual describes how to use SDF-A to create new syntax files or to modify existing syntax files.
The results of processing a syntax file with SDF-A become effective as soon as this syntax file is activated.
