Find every data set a job step allocates

Recipe IDio.moderne.mainframe.batch.FindJclStepDetail

Artifactio.moderne.recipe:recipes-mainframe

Report each job step in the order it runs and every DD it allocates, and mark the DD cards the report is drawn from: the data set, whether it is a generation, its disposition, and the record format, record length, block size, space and unit it is allocated with. Read with the procedure library supplied, the steps are the ones the job actually runs — a step that calls a procedure is replaced by the procedure's own steps, each naming the procedure it came from, with the job's DD overrides applied and its symbols filled in, so DSN=&HLQ..CLMMAST reads as the data set the catalog holds. What the programs do with each data set is carried across from the batch join. AnalyzeJclStepDetail answers the same question and changes nothing.

Column	Description
Job	The job name, empty for a member with no JOB card.
Member	The JCL member the job was read from.
Source path	The file the job was read from, which is the file to open at the line below.
Line	The one-based line the step's EXEC card is on. A step a procedure supplies is written in that procedure and has no line in the job, so it is the calling EXEC card that is given — the line the job's reader has. The procedure is read on its own as well, and its steps carry their own lines there.
Step number	Where the step falls in the job as it runs, procedures expanded, counting from one. Ordering by it is what makes the rows a step-by-step listing rather than a pile.
Procedure	The procedure the step is written in. Empty for a step written in the job itself; filled in with the procedure it calls when that procedure was not supplied, which is the one case where the step below it cannot be read.
Step	The step name, qualified by the step that called its procedure — EXTRACT.RUN — which is how a listing names it and how a DD override refers to it.
Program	The program the step loads, symbols filled in. A DL/I or BMP region names itself on PGM= and the program it loads in its PARM, and it is that program which is reported.
PSB	The PSB an IMS region step runs under, from its PARM. Empty for anything that is not one.
DD name	The DD name, which is the only word the JCL and the program both contain.
Data set	The data set as the installation knows it, with any member. A DD that concatenates several is one row each, because only the data set name joins one job to another.
Data set kind	Whether the DD names a catalogued data set, a generation, a library member, something temporary, in-stream data, DUMMY, SYSOUT, or a data set passed by an earlier step.
Generation	The relative generation of a generation data group, +1 for the one this step creates and 0 or -1 for one it reads. Empty for everything else.
Disposition	The DISP operand as written. The status is what says whether the step expects the data set to exist.
Record format	RECFM, from the keyword or from within DCB.
Record length	LRECL, from the keyword or from within DCB. 0 is written on purpose and is not the same as absent, so an omitted one is left empty.
Block size	BLKSIZE, from the keyword or from within DCB. 0 asks the system to choose one.
Space	The SPACE operand without its outer parentheses, CYL,(10,5),RLSE. Only a step that creates a data set writes one.
Unit	The UNIT operand, the device or esoteric group the data set is allocated on.
CRUD	The letters of everything the step's programs do to the data set — C, R, U, D, in that order. Empty where nothing in the run unit assigns the DD, or where the program was not among the sources read.

Source files that had results

org.openrewrite.table.SourcesFileResults

Column	Description
Source path before the run	The source path of the file before the run. null when a source file was created during the run.
Source path after the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changes	In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changes	The specific recipe that made a change.
Estimated time saving	An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
Cycle	The recipe cycle in which the change was made.

Source files that had search results

org.openrewrite.table.SearchResults

Search results that were found during the recipe run.

Export after a run

Column	Description
Source path of search result before the run	The source path of the file with the search result markers present.
Source path of search result after run the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Result	The trimmed printed tree of the LST element that the marker is attached to.
Description	The content of the description of the marker.
Recipe that added the search marker	The specific recipe that added the Search marker.
