I want to know do we have any data items or literals which defines all the valid character for COBOL. For e.g. NUMERIC means any numerals and ALPHABETIC means all alphabetic characters and some special characters. Similary do we have something that defines all the valid characters accepted by COBOL?

Hi,

You can compare your data-item as follows:

Data-Item is NUMERIC
ALPHABETIC
ALPHABETIC-LOWER
ALPHABETIC-UPPER
User-defined class name

Example:
In Input-data IS ALPHABETIC-LOWER
THEN
MOVE FUNCTION UPPER(Input-data) to Input-data
END-IF.

The UserDefinedClassName is name that a programmer can assign to a set of characters. The programmer must use the CLASS clause of the SPECIAL-NAMES paragraph, of the CONFIGURATION SECTION, in the ENVIRONMENT DIVISION, to assign a class name to a set of characters.
