Introduction:
Informational request for Telon compatibility with IBM APAR OA54807.
Question:
We need to research if any program product we support needs to have maintenance so it can work when we install the Meltdown/Spectre PTFs in OA54807. This APAR is implementing a new function called OSPROTECT that will control the Meltdown/Spectre CPU vulnerability. The Holddata specifies the changes that are being made and recommends that all ISV be checked for compatibility.
Environment:
Telon 5.1 
z/OS 2.2 
Answer:
Our Telon Sustaining Engineers did a  test with the IBM maintenance (APAR OA54807), and can report the following; 

Telon is an application program generator. It is used to create both COBOL and Pl/1 programs. The code generated by Telon has been tested with OA54807 applied and OSPROTECT set to 1. There were no problems during this testing.
