NFM mode OPEN changes cause S013 abend

Products

• Easytrieve Report Generator

Issue/Introduction

Why does an S013 abend under release 11.6 for not having DCB information for a dataset?

Environment

Easytrieve Report Generator, release 11.6

Resolution

Releases 11.6-C and 11.6 NFM act differently when it comes to the opening up of files within the Easytrieve program. 

With Easytrieve release 11.6-C, all files within the program are opened before processing starts. 
With Easytrieve release11.6 NFM, files are opened as they are referenced. 

Also files are opened in a different order:
With Easytrieve release 11.6-C, files are opened top down in the program. 
With Easytrieve  release 11.6 NFM, files are opened not only as they are processed, but how they are referenced in the Easytrieve JOB statement. 

In compatibility mode, Easytrieve did the OPEN, thus causing a blocksize value to be assigned to the file.  
Easytrieve release 11.6 only open files as they are processed.  
This is a known documented difference.
