Native Inspect Manual (H06.13+, J06.03+)

01 REC.
02 TABLE OCCURS 4 TIMES.
03 ITEM PIC 99.
88 ITEM-OK VALUE 12.
Any reference to ITEM-OK requires a subscript because any reference to ITEM requires a subscript.
For example, the following command evaluates and displays the second instance of ITEM-OK:
(eInspect 3,1012):print ITEM-OK(2)
Displaying Variables
Native Inspect follows COBOL rules for displaying numeric, alphanumeric, and edited data items.
Considerations are:
• Native Inspect does not allow the use of the PICTURE clause to format variables for display.
• You can display a variable in a different radix by using the FORMAT clause of the print and
x commands, as described in the section:Performing Machine-Level Debugging (page 54).
Displaying Level 88 Condition Names
Native Inspect displays Level 88 condition names as one of the values ‘T’ or ‘F’. The value displayed
depends on the value of the variable to which the condition belongs. For example, consider the
following declaration:
77 VAR PIC S99 VALUE 1.
88 COND-1 VALUE 1.
88 COND-2 VALUE -1.
The following Native Inspect commands display the values indicated:
displays the value ‘T’ because the value of COND-1 matches the value of
VAR.
print COND-1
displays the value ‘F’ because the value of COND-2 does not match the
value of VAR.
print COND-2
displays the actual value stored in VAR; in this case the value is 1.print VAR
Displaying Argument Values
By default, Native Inspect displays only the addresses of program and function arguments when
a breakpoint is encountered, a backtrace is done, or execution steps into a function. To display
the actual argument values on the occurrence of any of these events, specify the following command:
(eInspect 3,1012): set print cobol-arg-values on
Displaying Unprintable Characters
COBOL support is improved to display unprintable characters and substring searches. In previous
releases, Native Inspect would display unprintable characters using C programing format. For
example, a character with a value of 0 was displayed as \000. In this release, unprintable
characters are printed using COBOL Hexadecimal Nonnumeric Literals. For example, a character
with a value of 0 now displays as follows: X”00”.
Displaying the Length of the COBOL Variables
You can display the length of the COBOL variables using the print length command:
print length cobol-variable (or) print length (cobol-variable)
To print the length of an individual table element, subscript the table element. For example, consider
the following declaration:
01 MASTER.
02 TABLE-1 OCCURS 5 TIMES.
