Find references to a name

Report every place a data name, program, copybook, data set, DD name or paragraph is declared or referred to, with the file and line, and mark each one in the source. A search over the text finds the name wherever its letters appear; this finds the thing: a CALL through a field whose VALUE names the program, a condition name standing for the item it qualifies, a declaration copied in from a copybook, the DD a SELECT binds and the step that allocates it. What the rest of the portfolio knows about the name — what a program does with a field and where it reaches, who calls a program, who copies a copybook — is written beside its declaration.
