Data Locations
Data Locations
A data location is a symbolic reference to a data item within a program. Although the
syntax used to specify a data location varies for each source language, the general
syntax is the same for all languages.
scope-path
specifies the scope path to the scope unit containing the data item.
instance
specifies a specific activation of the scope unit containing the data item.
data-reference
specifies a data item using the syntax of the source language.
Usage Considerations
These considerations are valid for all source languages.

Modifying and Displaying Program Data
When program execution begins, the compilers add code in front of the first
program statement which initializes the run-time library and sets up the variables.
When you inspect a program, step to the first statement of your code before
accessing variables.

How Inspect Displays Names of Data Items
When Inspect displays the name of a data item (for example, when you direct
Inspect to display the value of a data item), Inspect uses a form similar to Pascal or
TAL. Assume you request Inspect to display the value of this COBOL data item:
hours OF overtime OF weeks-work (3)
Inspect displays its name as follows:
WEEKS-WORK[3].OVERTIME.HOURS

Specifying Subscript Ranges
When referring to arrays, Inspect enables you to specify a subscript range instead
of a single subscript value. For example, suppose the following data item occurs in
a COBOL program:
01 lumber-table.
03 thickness OCCURS 2 TIMES.
05 width OCCURS 6 TIMES.
07 price PICTURE 99V99.
