Issue/Introduction
Endevor C1DEFLTS table names the MCF datasets that hold the control data for each stage defined in the table.
Given an MCF dataset, would it be possible to determine to which stage it corresponds?
Resolution
Each MCF dataset contains a 'stage record' which is populated with information from the C1DEFLTS table the very first time that endevor opens the MCF. Printing that record shows information that may help to relate the MCF dataset with its C1DEFLTS table.
First step would be to print the stage record, which has a record key of 28 blanks (X'40'). This can be done, for example, with the IDCAMS utility:
//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
PRINT IDS(your.MCF.dataset.name) -
FROMKEY(' ') -
COUNT(1) -
DUMP
/*
The stage record contains the following information in the following columns:
- 001 - 028: Record key (blanks)
- 029 - 036: Previous stage name
- 037 - 080: Previous stage MCF name
- 081 - 088: Current stage name
- 089 - 132: Current stage MCF name
- 133 - 140: Next stage name
- 141 - 184: Next stage MCF name
- 185 - 185: Current stage ID
- 186 - 205: Current stage title
- 242 - 285: Element catalog dataset name
The above list refers to previous stage, current stage and next stage. Their meanings depend on whether the stage to which the MCF being listed belongs is stage 1 or stage 2 in its environment.
In both cases, "current stage" means the environment to which the MCF belongs, and then:
- If the MCF belongs to stage 1, previous stage is blank and next stage represents stage 2
- If the MCF belongs to stage 2, previous stage represents stage 1 and next stage is blank
Additional Information
The below example corresponds to IDCAMS PRINT of the MCF datasets belonging to the 2 stages of the same environment:
- For stage 1, its name is STG1, its ID is 1, its title is "STAGE 1" and its MCF DSN is PUBLIC.I3382506.STG1.MCF
- For stage 2, its name is STG2, its ID is 2, its title is "STAGE 2" and its MCF DSN is PUBLIC.I3382506.STG2.MCF
