Jim, Using READ will work fine until you try it on a very large sequential file and then you will run into "Memory Exceed" issues. Sometimes this will cause a Layer type 11 fault and crash your session.

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.

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.
