When a program has been written for a function, the system administrator must update the BIFTAB source, which is contained in SYSSRC.SDF-P-BIF.010. The BIFDEF macro generates a table entry which links the name of the function with the addresses of the executable module entry and the syntax specification entry.
The object generated for this BIFTAB module must be appended to the
SYSLNK.SDF-P-BIF.010 file. This deletes any earlier BIFTAB module. This new module will then be loaded by an automatic link the next time that the SDFPBIF subsystem is started.
The objects generated for the syntax specification and the function code must also be appended to the SYSLNK.SDF-P-BIF.010 file. They too will be loaded by an automatic link the next time that the SDFPBIF subsystem is started, but only if the entries in the BIFTAB module have been defined.
The functions thus appended can be accessed after the next start of the SDFPBIF subsystem.
