Issue/Introduction

Migrating consideration from Teleview to TPX. 
In Teleview, users can use ESC+enter to navigate to the Teleview menu retaining the keyed data in a CICS application.
In TPX, the ESC / ATTN key can be used for navigate to the Menu, however, why is the keyed data in a CICS application not retained ?

Environment

Release : 5.4

Component : CA-TPX for Z/OS

Resolution

In TPX the Esc / ATTN key is designed to mimic the ATTN key (signal) on a 3270 keyboard, while in Teleview the ESC+Enter is designed to mimic a 'navigational' key.
Image retention or screen updates are not a function of the 'signal' process in a standard 3270 keyboard. TPX provides the MENU key for that functionality.
Working as designed.
