Find the control flow between paragraphs and sections

Recipe IDio.moderne.mainframe.analysis.controlflow.FindControlFlowEdges

Artifactio.moderne.recipe:recipes-mainframe

Report every transfer of control between the procedures of a program as edges from MAINLINE, the statements before the first paragraph, down: PERFORM and each further procedure its THRU range runs through, GO TO including DEPENDING ON, the branch targets EXEC CICS HANDLE registers, and the fall-through from a paragraph that does not transfer away into the next. Each edge carries the line it is written at and whether it leads to a procedure that abends, with EXEC CICS ABEND or a call to CEE3ABD, so the error paths can be drawn apart from the rest. The graph is the one FindUnreachableProcedures walks, and programs containing ALTER are skipped for the same reason: ALTER retargets a GO TO at run time and leaves the program with no static control flow.

Column	Description
Program	The COBOL program.
From procedure	The paragraph or section control leaves, or MAINLINE for the statements before the first paragraph, where the program starts.
To procedure	The paragraph or section control reaches.
Kind	How control gets there: PERFORM; PERFORM_THRU for a procedure a THRU range runs through after its first; GO_TO; HANDLE for a branch EXEC CICS HANDLE registers; or FALL_THROUGH when the procedure before does not transfer away.
Line	The line of the statement that transfers control, or of the procedure fallen into. 0 when it was copied in from a copybook and so has no line in the program.
Column	The column that statement or procedure name starts in, counted from 1.
Abend target	Whether the procedure reached ends the run abnormally, with EXEC CICS ABEND or a call to an abend service such as CEE3ABD. Decided by what it does, not by what it is called.
