ACL/e is the scripting language used with CA TPX.
How to execute a CA TPX ACL script within an ISPF session?
To start an ACL/E program manually, you issue the ACL/E start command "S" in the command field of the ISPF panel.
To do this, type your CA TPX command character, an S, a blank, and the name of the ACL/E program followed by pressing the command key.
For example, if command character is / and command key is PF12 =>>> /s myacl<PF12>
