The literal which you have specified in the CURRENCY SIGN IS clause in the SPECIAL-NAMES paragraph of your program is not
one of those permitted under the rules of COBOL syntax, or if it is then you have failed to enclose it in quotation marks.
The literal must be a single character, not a digit, and cannot be any of the following, A B C D L P S V X Z * + - , . ; (
) " / = or space (except in ANS85 where L is valid).
Change the literal to a permitted character and ensure that it is enclosed in quotation marks.
