SSPBK Prolog

 Name       : HCPSSPBK
 Description: Pointer block to SSBDF blocks
 STATUS     : VM/ESA Version 2, Release 1.0
 DSECT      : SSPBK
 Function   : The chain of SSPBKs acts as the trunk of the syntax
              tree defined by the invocation of the HCPDOSYN macro.
              The SSPBKs point to the SSBDF blocks, which anchor
              the branches of the syntax.
 Located by : SYNSSPPT created during expansion of HCPDOSYN macro.
              SYNSSPPT changed as a result of the EXTERNAL_SYNTAX
              statement in the SYSTEM CONFIG file.
              SSPFWD   created during expansion of HCPDOSYN macro.
              SSPFWD   changed as a result of the EXTERNAL_SYNTAX
              statement in the SYSTEM CONFIG file.
 Created by : Invocation of the HCPDOSYN macro.
              HCPZPUES as a result of the EXTERNAL_SYNTAX
              statement in the SYSTEM CONFIG file.
