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.
