Re: COBOL400-L Digest, Vol 1, Issue 233

To validate the 15 character field, to check the 1st 4 character for
numeric, you could do this:
01  MISC-AREA.
      05   VNCOMPANY  PIC X(15).
  05 VNCOMPAY-NAME.
     10  VNCOMPANY-ALPHA  PIC X(04).
     10  VNCOMPANY-BLANK  PIC X(11).

MOVE VNCOMPANY(1:4) TO VNCOMPANY-ALPHA.
MOVE VNCOMPAY(5:11) TO VNCOMPANY-BLANK
IF VNCOMPANY-ALPHA IS NUMERIC AND VNCOMPANY-BLANK = SPACES
      (THEN THE 1ST 4 CHARACTERS ARE NUMERIC AND BYTES 5 - 15
       ARE. THIS IS A VALID COMPANY)
-------------------------------------------------------------
OR THE CODE BELOW WILL WORK

IF VNCOMPANY(1:4) IS NUMERIC AND VNCOMPANY(5:11) = SPACES
      (THEN THE 1ST 4 CHARACTERS ARE NUMERIC AND BYTES 5 - 15
       ARE. THIS IS A VALID COMPANY)

subject: Testing for valid numeric in an alpha field

I know how to do this in RPG but not Cobol:

I've got a 15-character alpha that is supposed to contain a 4-digit number
left-justified.  In my
Cobol program, VNCOMPANY is a 15-character alpha field and WS-VND-COMPANY
is a 4-digit numeric.
When I do this:
    MOVE VNCOMPANY TO WS-VND-COMPANY.
and VNCOMPANY contains '40             ', I get a decimal data error.

In RPG, I'd use a MOVEL and a TESTN.  Off the top of my head, the only way
I can see doing this in
Cobol is to check the first four bytes of the field individually to be in
the range of '0' through
'9'.  (Bytes 5-15 would have to be blank for our validation purposes.)

Any suggestions?

TIA, Dan

If you are sure you have numeric data in VNCOMPANY then the below statement
will do what you want.

COMPUTE WS-VND-COMPANY = FUNCTION NUMVAL(VNCOMPANY)

Dan,
To prevent a decimal data error when the field does not contain numerics,
redefine the receiving field and test for numerics before performing any
calculations.

05   ws-vnd-company     pic 9(04).
05   ws-vnd-company-x refefines  ws-vnd-company   pic x(04).

MOVE VNCOMPANY TO WS-VND-COMPANY.
if ws-vnd-company-x not numeric
   move zeros to ws-vnd-company.

Dan,
Oops...
I should have said move vndcompany to ws-vnd-company-x.  This will
accomplish the same result as a MOVEL.


To prevent a decimal data error when the field does not contain numerics,
redefine the receiving field and test for numerics before performing any
calculations.

05   ws-vnd-company     pic 9(04).
05   ws-vnd-company-x refefines  ws-vnd-company   pic x(04).

MOVE VNCOMPANY TO WS-VND-COMPANY.
if ws-vnd-company-x not numeric
   move zeros to ws-vnd-company.
