While trying to solve the Scrabble Scores exercise on Exercism, I read in
the GnuCOBOL FAQ about CLASS in SPECIAL-NAMES. Is this an okay use
thereof?

IDENTIFICATION DIVISION.
PROGRAM-ID. SCRABBLE-SCORE.
ENVIRONMENT DIVISION.
CONFIGURATION SECTION.
SPECIAL-NAMES.
CLASS ONES IS 'A', 'E', 'I', 'O', 'U', 'L', 'N', 'R', 'S', 'T'.
CLASS TWOS IS 'D', 'G'.
CLASS THREES IS 'B', 'C', 'M', 'P'.
CLASS FOURS IS 'F', 'H', 'V', 'W', 'Y'.
CLASS FIVES IS 'K'.
CLASS EIGHTS IS 'J','X'.
CLASS TENS IS 'Q','Z'.
DATA DIVISION.
WORKING-STORAGE SECTION.
*Inputs
01 WS-WORD PIC X(60).
01 WS-WORD-ARRAY REDEFINES WS-WORD.
03 WS-CHAR PIC X OCCURS 60 TIMES INDEXED BY CHAR-INDEX.
*Outputs
01 WS-RESULT PIC 99.
PROCEDURE DIVISION.
SCRABBLE-SCORE.
INITIALIZE WS-RESULT.
MOVE FUNCTION UPPER-CASE (WS-WORD) TO WS-WORD.
SET CHAR-INDEX TO 1.
PERFORM LENGTH OF WS-WORD TIMES
IF WS-CHAR(CHAR-INDEX) EQUAL SPACE

EVALUATE WS-CHAR(CHAR-INDEX)
WHEN IS ONES
ADD 1 TO WS-RESULT

WHEN OTHER ??

You could probably put the test for SPACE in there, something which
would remove any chance of a test on WS-CHAR (61).

Yes, good advice. Thank you.

Just paranoia, 60 letters for one word is ridiculous, but I have no idea
where the data comes from.

Bingo. Data are dirty unless proven otherwise. What you're using SPECIAL-NAMES for we used to do with 88s that ran on for pages.

01 WS-TEST-INVOICE-DISTRICT PIC 9(6) VALUE ZEROES.
COPY VALDSTRC.

MOVE IV97928-INVOICE-REC TO WS-INVOICE-REC.
MOVE WS-INVOICE-REC-DISTRICT TO WS-TEST-INVOICE-DISTRICT.
IF VALID-DISTRICT
NEXT SENTENCE
ELSE
PERFORM 8100-INVALID-INV-DSTRCT THRU 8100-IVD-EX
GO TO 9999-CLOSE-N-EXIT.

.... and The Guy in the Corner Cubicle - back in those days it was always a guy - had a list in the top-right drawer of his desk with the names of all
the programs that had to be recompiled every time a new district was
acquired.
