Hello Team,

I'm trying to automate a task within a Mainframe application using the HOST3270S1 Client.

To log in, users are required to type their credentials and then press the Enter key. My issue is with the Automation Anywhere Terminal Emulator actions: the Send Keys action does not seem to contain an option for the Mainframe 'Enter' key (I'm specifically referring to the transmit/process key, not a line 'Return' key).

Could anyone please advise on how to correctly simulate this specific Enter key press within Automation Anywhere's Terminal Emulator?

In the Send Keys action, the KEY_ENTER is the enter key on the right side of the keyboard.

A regular carriage return is $String:Enter$, which you can send with the Send Text action.

​@Aaron.Gleason 

Thanks! It works. I used the Send Text action with [ENTER] and it resolved the issue
