RE: Matching Records

From: Joep Beckeringh

Actually it should be:

if not *inmr or
(*in02 and (file1data1 <> file2data1) or
(file1data2 <> file2data2) or
(file1data3 <> file2data3) or
(file1data4 <> file2data4));

Otherwise your program will fire for every record in the primary file.

Yup, you're right Joep. It has been a while <sheepish grin>. At 01NMR time
the secondary file hasn't been read yet. I don't know what I was thinking.
So you can only check for differences on the secondary record.

In your example, which is very concise, I remember
that you need to specify end of file processing on
both the primary and secondary files or the program
will end once all records are read from the primary
file regardless if more records remain in the
secondary file. So the file spec would be IPE for the
primary and ISE for the secondary. Maybe someone else
remembers this subtlety or has additional light to
shine on the topic.

As Joep pointed out, when all the EOF fields are blank, all records are
processed. I tested it with my little program after adding data to the file
(and realizing that Joep was dead-on about adding the *IN02 qualification).
