Expressions
However, if you compile your program using the WITH DEBUGGING MODE clause in
the SOURCE COMPUTER paragraph, these data item is available:
DEBUG-ITEM is mainly used for non-interactive debugging, but the PROGRAM-
STATUS and GUARDIAN-ERR registers can be helpful in debugging with Inspect.
Expressions
Here is the syntax you use to create COBOL expressions in Inspect.
Usage Considerations

Operator precedence is the same as the precedence defined in COBOL.

When you use the minus sign (-) as an operator, you must delimit it with spaces.

Inspect does not support these in expressions:
Class conditions, such as ALPHABETIC and NUMERIC
Sign conditions, such as NEGATIVE and POSITIVE
Figurative constants, such as HIGH-VALUES, SPACES, and so on
Abbreviated compound conditions, such as (A > B OR C)
DEBUG-ITEM Is a part of the ANSI Standard debugging mechanism. For more
information, see the description of the USE statement in the
COBOL85 for NonStop Systems Manual.
