This Post Will Provide You With Enough Tools To Build Your First Nofile Enquiry.
Introduction:

Often ‘Enquiries’ need to read, take and sort data from more than one file.
Only one Filename can be given in the ‘Enquiry’ application.
Such requirements can be met by attaching ‘subroutines’ that pass the required sorted information to the ‘Enquiry’ (NOFILE Enquiry does this)
No file Enquiry that will allow us to pick up data from multiple files.
This can be achieved by writing a Subroutine that will pick up the necessary data and pass it on to the Enquiry subsystem for processing.
The document attached below will give you detailed understanding and insight to the workings of an Enquiry.
I have also attached a sample program you can use to develop your first Nofile Enquiry.
