Build the call tree

Recipe IDio.moderne.mainframe.calltree.FindCallTree

Artifactio.moderne.recipe:recipes-mainframe

Lay out every job, procedure, program and subprogram of the portfolio as a tree from what runs it: a job's steps, the procedure or program each step runs, the steps of that procedure, and the programs each program reaches by CALL, EXEC CICS LINK or XCTL, one row per position and depth first so the rows alone draw the tree. A step names a load module rather than a program, and where a link-edit deck says what is bound into it the module is a position of its own with every program it holds beneath it. A target named by a data item is resolved through the one literal the item is given where there is one, and flagged as dynamic either way. A tree starts from each job and from each procedure and program nothing reaches; a node already in its tree is written where it is reached again and not expanded, which is what keeps a cycle finite. Every step and every CALL, LINK and XCTL is marked.

Data tables

Call tree

io.moderne.mainframe.analysis.table.CallTree

Every job, procedure, program and subprogram as a tree from what runs it, one row per position and depth first, so the rows alone lay the tree out.

Export after a run

mod study . --last-recipe-run \
  --data-table io.moderne.mainframe.analysis.table.CallTree

Column	Description
Root	The job, procedure or program the tree starts from.
Depth	How far below the root this position is, 0 for the root itself.
Parent	The node this one is reached from, empty for the root.
Node	The job, step, procedure or program at this position. A transfer whose target is only known at run time names the data item that holds it.
Node type	JOB, STEP, PROC, LOAD_MODULE for what a step runs where a link-edit deck says what is in it, PROGRAM for what a step runs or a LINK or XCTL reaches, and SUBPROGRAM for what a CALL reaches.
Edge kind	How control gets here from the parent: STEP for a step of a job or procedure, EXEC for what a step runs, INCLUDE for a program bound into the load module above it, CALL, LINK or XCTL. Empty for the root.
Dynamic	Whether the target was named by a data item rather than written, resolved through the one literal the item is given where there is one.
Repeated	Whether the node already appeared earlier in this tree, in which case what it reaches is not written again. That is what keeps a cycle finite, and what a layout draws grayed.

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.

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.
