Cross-Reference Listing

Figure 1 shows the cross-reference listing, which is produced when the XREF option is specified. It provides a list of all data references, procedure-name references, and program-name references, by statement number, within the source program.

Procedure References:
Context usage is indicated by the letter following a procedure-name reference.
These letters and their meanings are:
    A = ALTER (procedure-name)
    D = GO TO (procedure-name) DEPENDING ON
    E = End of range of (PERFORM) through (procedure-name)
    G = GO TO (procedure-name)

Program References:
Program-type of the external program is indicated by the word in a program-name definition.
These words and their meanings are:
    EPGM = a program object that is to be dynamically linked
    BPRC = a COBOL program or a C function or an RPG program that is to be bound
    SYS  = a system program

The cross-reference listing displays the following fields:

T: Names field: The data name, type name, procedure name, or program name referenced is listed here. The names are listed alphabetically. Program names may be qualified by a library name.
U: Defined field: The statement number where the name was defined within the source program is listed here.
V: References field: All statement numbers are listed in the same sequence as the name is referenced in the source program. An * following a statement number indicates that the item was modified in that statement.
