Re: Converting Character Zoned Data to Numeric in SQL

Jerry,

Thanks for the info.

BTW, I also programmed on a Burroughs (a 7700, IIRC) many years ago
(also, don't ask), when I was helping a friend of mine at the
University. We coded in PL/1 and it really was a joy when someone
(mostly the system's operator) dropped our card stack just before
feeding it to the computer (no, no really...)

It has been many years since I have had to worry for zone and digits
portions of a field...

BTW, in our system (V5R3) , a negative ZONED field registers as N.

The displayed value (DSPPFM) of a signed field is a combination of the

zone and digit portions of the byte. The result, ergo, will depend upon the
value of the digit portion since, for a negative value, the zone is always a
'D'. On a display file panel, if one does not leave room for the sign on
the right, the character value (J-R, }) will be displayed; otherwise, the
numeric value will be displayed with the sign at the right.

I started out on a Burroughs system (don't ask) years ago. The sign for

numeric fields was LEFT justified (i.e., in the first byte whether packed or
unpacked). When we converted to a S/3, we had to write a program to convert
the sign to the RIGHT most byte.
