 FUNCTION   : The SSBDF acts as a branch of the syntax tree defined
              by the invocation of the DOSYN macro.  The DOSYN
              macro, in turn, creates the syntax tree branch based
              on invocations of CFDEF, STDEF AND TKDEF macros.
 Created by : invocation of the DOSYN macro.
