Re: soft coding parameters

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

RCVF will continue to work but it will start at the first record and 
read each one sequentially until the end of the file.  I think you might 
want to key the file so the records arrive in newest to oldest sequence 
then only the first read would be needed.  Any other method of 
retrieving the record would work as well.

I did not see if you are at V7 or not but the new RUNSQL statement might 
help with retrieving the correct row from the table.   It's a bit easier 
than OPNQRYF.
