Thanks for all the suggestions.
I felt most comfortable with doing a quick OPEN, a READ, followed by a
DCOUNT(REC,@FM) then a CLOSE F.FILE prior to the OPENSEQ.
The reason for this approach is that I wanted to know if the number of
READSEQ's needed to read the file would be greater than one, prior to
attempting a second READSEQ.

Subject: Field
Count from a Seq File
Tuesday June 21, 2005 03:37 PM
I hope someone can show me an easy way to get the number of lines from a
sequential file - without looping through the file.
I am running UV 10.x on a AIX box.
I open the file using an OPENSEQ command and I am looping through the
record using a READSEQ command.
Either immediately after the OPENSEQ or after the first READSEQ, I would
like to know if there is more then 1 line in the file.
I know that prior to doing the OPENSEQ, I could open the file, read the
record and then DCOUNT(RECORD,@FM) to get the number of fields, close the
file and then do a sequential open and read. I am hoping that there is a
system variable or something that I can use after the OPENSEQ. Looping
through the record is not a viable option.
Thanks
Jim
