Subject:   Using FIRSTOBS on a PDS

Hi,

Any OS/390 sites seen this?

Code:- DATA test; infile 'td.sl839f.listjm3(upyld)' firstobs=3 obs=3; input @2 rprtdate ddmmyy10.; code... run;

Picks up the third record OK but in the wrong block so a PDS with a blocking factor of say 100, it goes and gets record 203!

Still to fully analyse this but it always seems to be the last block it's using - in the example above there are only 220 records, seems that if we up the records to say 450 then records 403 is obtained (at least I think that's what's happenning).

Same file on a sequential file is fine - it's just PDSs. The PDS is

PO FBS LRECL=133 BLKSIZE=23674 DIR BLOCKS=200

but we've tried it on other sizes and it still skips the first block.

Newly upgarded to SAS 6.09 (Ts455) so SAS is getting the blame for this.

Anyone seen anything like it?
