With ACL/E LMP key active, you will see this messages in the TPX startup:
TPX9925 OPTION ACLE OF UNICENTER CA-TPX IS AUTHORIZED
When you remove the LMP keys, these messages will disappear after the next IPL.
If you are not authorized for ACL/E then you have no scripting ability within TPX. If you are doing any scripting at all, you would be using ACL/E. (For example: Application Start or Terminate ACL, etc.)
