I'm writing a little program that needs to know the number of records in a standard ascii file on a VAX running VMS 4.4. I am reading until EOF and counting them now, but I would like a faster way if possible. Thanks in advance, Tony Andrea Sierra Geophysics, Inc.

For a file of fixed length records you can specify a user-open routine, request xabfhc on $OPEN, and calculate the number of records in the file. I don't know of any way to get the number of records in a file of variable length records such as a text file. Phil Young

No record is kept of the number of records in a "standard ascii file", which
I take to mean a file with variable-length records (so that you can't just
look at total size and divide by the length of a fixed record). What you are
doing is the only after-the-fact approach possible. (If you are the one
writing the file, you can of course keep track yourself and store the infor-
mation away.)
