Reading Sequential file with no CR/LF in records

[TonyG]

Hello,

Environment is standalone PC using MF COBOL 3.0 and DOS 6.22. When i try to read a single record from a file that is defined with the following Select and FD, it opens the file ok, but when i try to read the record in it, it returns a FS=10.

I don't really know what the file/record size is except that a DOS DIR yields 58 and looking at the file in an editor shows the last character in the file at location 58 (a comma ",&quot with no CR/LF's.

I tried various combinations of RECORDING MODES, FIXED/VARIABLE LENGTH, SEQUENTIAL/LINE SEQUENTIAL. The closest i can come to getting to read a record is the current definition:

Thanks for any help with this problem.
Tony

Hi,

In the program hereafter, I read a DBase file and convert it into a sequential file.

It is a kind of binairy read, so it should work.

Good Luck!
