Hi,

Can someone tell me the valid set of ALPHABETIC-UPPER in cobol?

For Example: valid set for NUMERIC is : 1 2 3 4 5 6 7 8 9 0

What is set for ALPHABETIC-UPPER??

I also checked existing post regarding same but didn't find anything similar to this.

Thanks,
Narendra

Is this a trick question?

Letters "A" through "Z".

Note that in the EBCDIC collating sequence (unlike ASCII), these values are NOT consecutive.

X'C1' --- X'C9' (A-I)

X'D1' --- X'D9' (J-R)

X'E2' --- X'E9' (S-Z)

Bill

Good day to all!

Alphabetic-upper is a CLASS clause use in SPECIAL-NAMES. Alphabetic-upper is A thru Z and space.

In OS/VS COBOL, only uppercase letters and the space character were considered to be ALPHABETIC.

In Enterprise COBOL, uppercase letters, lowercase letters, and the space character are considered to be ALPHABETIC.

If your OS/VS COBOL program uses the ALPHABETIC class test, and the data tested consists of mixed uppercase and lowercase letters, there can be differences in execution results. In such cases, you can ensure identical results by substituting the Enterprise COBOL ALPHABETIC-UPPER class test for the OS/VS COBOL ALPHABETIC test.

Thats why you need to use it in SPECIAL-NAMES.

You should also be aware that in some code page representations national characters and most special characters will be outside the ALPHABETIC class.
