Build the resource CRUD matrix

Recipe IDio.moderne.mainframe.analysis.FindResourceCrud

Artifactio.moderne.recipe:recipes-mainframe

Report which programs create, read, update and delete which files, queues, DB2 tables and IMS segments. A mainframe program reaches its data four different ways — CICS commands, DL/I calls, embedded SQL and native file I/O — and each is normally reported on its own, which is what makes "who else writes this" hard to answer. Here a VSAM file read through CICS in one program and through READ in another is one resource with two readers.
