Reply with quote

Hi,

I have a problem with the rewrite of VB record in PL1.

The file properties are RECFM=VB, LRECL=800.

I have read a record into 796 structure. Then based on some condition, i have modifies two fields (in the read record with no change to the length) and then tried to rewrite the record.

It is giving an error message (Record Length is greater) in the rewrite statement.

Can you please advise on this problem?

Thanks,
Sreenivas

What are the actual error messages and codes issued, and what does it say in the manual regarding these.

Also, do you READ INTO or READ SET(pointer)?

Garry.

This works, adapt to your needs:

Code:

test: proc options(main) reorder;
dcl sysprint file;
dcl infile   file record update env(vb recsize(800));
 
dcl 1 * union,
      2 inrec      char     (796) var,
      2 *,
        3 *        fixed bin (15),
        3 yourrec,
          4 f1     char       (4),
          4 f2     char       (3);
 
read file(infile) into(inrec);
f1 = 'XXXX';
rewrite file(infile) from(inrec);
 
read file(infile) into(inrec);
f2 = 'XXX';
rewrite file(infile) from(inrec);
end test;


Don't know what unions are? RTFM!
