MODIFY

When you request information about all identifiers in a program unit, Inspect lists
the identifiers in the reverse order of declaration for COBOL 74 and COBOL85;
Inspect lists the identifiers in alphabetical order for SCREENþCOBOL.
MODIFY

A MODIFY command operating on an edited field does not edit. Inspect functions
just as the VALUE clause does, inserting a character value into the data item
unchanged.

When you use a MODIFY command to assign a value to a group item, you must
use the MODIFY WHOLE form. The value you provide in the command must be a
quoted string value.

When you specify the name of a group item in a MODIFY WHOLE command,
Inspect requires the new value to be in the command list. Inspect will not prompt
for a new value.

When an alphanumeric data item in a COBOL program is being modified, the &
operator can be used to concatenate bytes with a string. The values can be in
binary, octal, or hex format.

The MODIFY command does not restrict COMPUTATIONAL items to 18-digit
values; it will allow you to store a 19-digit value. However, COBOL cannot
manipulate COMPUTATIONAL values in excess of 18 digits.

The MODIFY command can modify COBOL items that have been declared in the
Extended-Storage Section. To modify these items, use the standard MODIFY
command syntax described in Section 6, High-Level Inspect Commands.
SCOPE

For COBOL, the scope of an identifier is always the program-ID of the program unit
in which the identifier is declared.

If you have identifiers of the same name in different program units, be sure that you
qualify the identifiers enough for Inspect to distinguish them.
SET RADIX

Even if you set your input radix to hexadecimal, you must still prefix a hexadecimal
value with zero or “%H” if its first digit is above nine; otherwise, Inspect interprets
the value as an identifier.
STEP

The STEP command considers COBOL CALL, ENTER, and PERFORM
statements as one verb. If you step through a portion of the program and come to
a PERFORM statement, a subsequent STEP 1 VERB command executes the
