On Screen Update

This option activates the script (if activation is allowed) every time the text on the emulation screen changes. This includes updates from the host or when the user presses a key and the key value is shown on the screen. It is recommended that you limit the host profiles that the script supports.

The following example generates a script that enters a command each time a particular string appears on the screen:

Label:Start:
If (String_Equal(Get_Screen_Text_Columns(1,1,5),"Ready", 0,FALSE))
Keypress_String("Proceed")
Keypress_Key("Enter")
End_If
Wait_For_Screen_Update
Goto: Start
Return

If the script is set to activate when the session first connects, it will work as desired with one limitation. Because it is always activated, no other scripts can be activated during the emulation session.

Here is an alternate implementation:

If (String_Equal(Get_Screen_Text_Columns(1,1,5), "Ready", 0, FALSE))
Keypress_String("Proceed")
Keypress_Key("Enter")
End_If
Return

If the script is set to run each time the screen updates, you get the desired behavior. Because the script is not active all the time, other scripts can be activated as well.

Use this option carefully as it can cause a script to be executed frequently.

To configure the On Screen Update method:

1  Select the General tab or Activate tab in the Script Editor.

2  Enable the On Screen Update option.

3  Click OK.
