The answer is No, they are not the same thing.
CA Telon is a mainframe-target application Generator. The CA Telon Design Facility (TDF) is used to paint a screen or report, define screen and DBMS I/O, and add "custom code" (exit points that can be used to add business-based code).
The CA-Telon Test Facility (TTF) provided an INTERACTIVE debugging tool that allowed you to test an application or prototype new screens in the MVS mainframe environment.
However, due to the constraints of its underlying architecture, the CA Telon Test Facility is no longer supplied or
supported as part of the product.
We recommend you consider CA-Intertest Batch for your debugging needs in batch and IMS programs.
