numeric and string variables, usage is also

characterized by the location of the declaration of the

variable in the program, PARAMETER, or COMMON. If

neither of those is specified, the variable is local.

Identifiers that are not variables are characterized by

their usage in the program as SUBPROGRAM, FUNCTION,

EXTERNAL, or LABEL.

Type The data type of the identifier: SHORT REAL, REAL,

SHORT INTEGER, INTEGER, SHORT DECIMAL, DECIMAL, or

STRING.

Declaration Whether the numeric or string variable has been

explicitly declared.

Occurrence The line numbers of the statements that the identifier

occurs in. The line numbers of statements in which a

new value is potentially assigned to the identifier are

followed by an (*). The line number of the statement

that the identifier is declared in is followed by an

ampersand (@).

If either WITH LIST or WITH SOURCE is specified, the formatting of the

cross reference's output is controlled by any of the compiler options

such as LINES, LIST, PAGE, PAGESUB, TITLE, and TITLESUB present in the

program. Otherwise, the default compiler options are in effect.

NOTE Because of the large amount of internal information that must be

evaluated when creating a cross-reference, a cross-reference for a

large program can take a considerable amount of time. As a result,

there may be a long delay before the first output is printed or

displayed.

The following is a sample output of the cross reference:
