 Name       : HCPDGSBK
 Description: Directory generic string block
 DSECT      : DGSBK
 Function   : The directory generic string block contains a
              character string created by a directory
              statement processed by HCPDIR.
 Located by : On DASD - DVMDWDAD/DVMDWDSP fields of HCPDVMD
              DVMDUDAD/DVMDUDSP fields of HCPDVMD
              DVMDRDAD/DVMDRDSP fields of HCPDVMD
              In storage - DVMDWDAD field of HCPDVMD
              DVMDUDAD field of HCPDVMD
              DVMDRDAD field of HCPDVMD

 Comments   : This block is used to contain various
              string (text) fields in the object directory.
              The DGSLABEL field identifies which string a
              specific instance of this block contains.
              An "in-storage" copy of this block may contain
              data from the online directory or an ESM.
