How is it work X(5) > X(5) = ?

Hi,

I have an variable declaring like,

05 TERR-CD1 PIC X05) VALUE '100'.
05 TERR-CD2 PIC X05) VALUE '200'.

I JUST TRY TO COMPARE THIS ALPHA NUMERIC VARIABLES,

IF TERR-CD1 > TERR-CD2
DISPLAY 'A > B'
ELSE
DISPLAY 'B > A'
END-IF.

IT'S WORKING FINE. I GAVE THE RESULT AS B > A

I JUST WANT TO KNOW, HOW IT IS COMPARING ALPHA NUMERIC, WITH OUT CONVERTING IT INTO NUMERIC. IS THIS ALPHA NUMERIC COMPARE ALWAYS WORKING CORRECTLY OR ANY CONSTRAINT IS THERE?

Hello and welcome to the forums

You defined character fields and the system did a character compare. There is no numeric involved.

If you want to do numeric compares, you must tell the system you want to work with numbers rather than characters.

If that is not clear, please let us know.

Hello Pons,

Do you have an answer for your question?

I believe we've explained what happened, but i'm not sure that is your complete question.

Please let us know if you'd like additional info.

Hi,

Thanks for your clarifications. I got my answer. William Thompson explained with hex decimal and binary.

But one more doubt. Normally the characters are storing form the left to right i guss. But William, you mentioned as

X'4040F1F0F0'
spsp1 0 0
X'4040F2F0F0'
spsp2 0 0

Is it storing in the above format or its like,

X'F1F0F04040'
1 0 0 spsp
X'F2F0F04040'
2 0 0 spsp

Please let me know.
