Find what the run books document

Recipe IDio.moderne.mainframe.documentation.FindRunBooks

Artifactio.moderne.recipe:recipes-mainframe

Report what a documentation library says about the estate around it: one relationship row per name a run book member writes that the portfolio answers to, typed by what the name turned out to be, and one coverage row per program and job saying which member documents it. A run book is prose written in upper case, so a name-shaped token in it is any word of eight characters or fewer and no rule tells MASTER in a sentence from MASTER in a library: what makes a name a reference is looking it up among the members, data sets, tables, databases and load modules the portfolio holds, which is a join rather than something one member says. The row for what a member is about carries its shape — DOCJOB, DOCPGM, DOCFICH, DOCAPPL or DOCOPER — as the action metadata, so the component it documents can be told from a name it merely mentions. Both directions are findings as well: a program with no run book, which is worth knowing before touching the program, and a run book whose subject nothing answers to, which is a member a rename left behind. Every line writing a name that resolved is marked, which is what a reader is looking for in a page of prose.

Data tables

COBOL relationships

org.openrewrite.mainframe.cobol.table.CobolRelationships

Relationships between different COBOL resources.

Export after a run

mod study . --last-recipe-run \
  --data-table org.openrewrite.mainframe.cobol.table.CobolRelationships

Column	Description
Dependent	The resource that defines the relationship.
Dependent type	The resource type of the resource that defines the relationship.
Action	The action that links the dependent and dependency.
Dependency	The resource that is exercised or linked to.
Dependency type	The resource type of the resource that is exercised or linked to.
Dependency missing	Indicates whether the dependency is a known resource.
Action metadata	Additional data about the action.
Dependent path	The source file the dependent's statement was written in, or null when the dependent is a name that has no source here.
Dependent line	The one-based line the dependent's statement was written on, or null when it has no source here.
Dependency path	The source file the dependency was written in, or null when the dependency is a name that has no source here, such as a vendor copybook.
Dependency line	The one-based line the dependency's statement was written on, or null when the dependency is a whole file rather than a statement within one.

Run book coverage

io.moderne.mainframe.analysis.table.RunBookCoverage

Every program and job of the portfolio with the run book member that documents it, and every run book with the component it is about.

Export after a run

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

Column	Description
Component	The program, job or data set: the PROGRAM-ID, the JCL member name, or the data set name a DOCFICH carries on its FILE line.
Component type	What the component is, in the relationship model's vocabulary: COBOL, ASSEMBLER, SAS, JCL or DATA_SET.
Source path	The file the component is in, or empty where nothing in the portfolio answers to the name.
Run book	The documentation member, or empty where none documents the component.
Shape	Which kind of run book it is, from its own first word: DOCJOB, DOCPGM, DOCFICH, DOCAPPL or DOCOPER.
Run book path	The file the run book is in.
Verdict	DOCUMENTED, UNDOCUMENTED for a component no run book is about, or SUBJECT_MISSING for a run book whose subject nothing answers to.
Names resolved	How many of the names the run book writes down are components of the portfolio. A run book is prose, so what it mentions over-answers until it is looked up; this is what survived the lookup.

Findings

io.moderne.mainframe.analysis.table.Findings

Everything the mainframe analyses found wrong, ranked, with the evidence for each and the line it is on. Sort on priority.

Export after a run

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

Column	Description
Priority	1 for CRITICAL down to 4 for LOW, so the table sorts.
Severity	CRITICAL for code that cannot do what it was written to do, HIGH for what will break a migration if not decided deliberately, MEDIUM for what is worth knowing first, LOW for cleanup.
Category	What kind of problem it is, which is what groups the report into sections: DEAD_RULE, UNREACHABLE_CODE, COPYBOOK_DRIFT, MIGRATION_BLOCKER, RANGE_PATHOLOGY, DEAD_DATA, COMPLEXITY, LAYOUT_DRIFT, IMS_PCB_MISMATCH, IMS_SEGMENT_NOT_SENSITIVE, IMS_IO_AREA_MISMATCH, MFS_MESSAGE_LENGTH, SCREEN_ITEM_UNREACHED, SCREEN_FIELD_UNREACHED, PARSE_FAILURE, UNDOCUMENTED, STALE_DOCUMENTATION, STALE_REFERENCE, UNENFORCED_BUILD_ORDER, UNSCHEDULED_JOB, AUTOCALL_RESOLVED_REFERENCE, UNRESOLVED_EXECUTION_PATH, INHERITED_SETTING, UNLOAD_NEEDS_REDESIGN, UNLOAD_ACCESS_MODE, UNLOAD_CONSISTENCY, UNLOAD_OUTPUT_WIRING, MIXED_SUBSTITUTION.
Program	The COBOL program, or the copybook where the finding is about one.
Summary	The finding in one sentence, written to be read on its own.
Evidence	Why this is claimed — the conditions that conflict, the two declarations that differ, the caller that made the paragraph unreachable. A finding nobody can check is a finding nobody will act on.
Where	The paragraph, section or data item the finding is in.
Source path	The file, so the finding can be opened.
