Re: Record format level mismatch question

[smorrison@xxxxxxxxxxxxxxxxxxx]

Your programs may produce different results if you make the changes you 
listed, but the record format identifier has not changed. The record 
format identifier is a hash total of some sort, based on the number of 
fields, the length of each field, the field attributes and edit codes. 
Selecting a different key order, or a different select/omit criteria 
doesn't change the format of the data in the file.

What is your recommendation, suppose I change my selection criteria and 
add a another key and compile what will happen to my programs?

Level Check (*NO)  is never a good idea.

I find it hard to believe anyone still would recommend it.
