Sets the name of the ACB to be used when establishing a session with the application.
This common session parameter is applicable to these control statements: PROFILE (see PROFILE statement), USER (see USER statement), TERMINAL (see TERMINAL statement), and APPL (see APPL statement). It is not applicable to the SYSTEM control statement.
This parameter, which can be up to a maximum of eight bytes long, provides a method of overriding the normal IBM Session Manager ACB allocation process, which is fully described in the section 'Choosing an ACB' in the chapter 'Setting up applications' of the Installation and Customization manual.
The override_acbname may contain the special character '?' (question mark symbol) in any number of positions, and IBM Session Manager substitutes these with the corresponding characters from the LU name of the terminal. For example, if the LU name is L010ABCD, and an override_acbname of ????K1 is specified for the ACB parameter, the ACB name L010K1 would be generated.
Although it is not a recognized key in all countries, a hash (#) is allowed in place of a question mark, for backwards compatibility.
Note: Since '?' is itself a IBM Session Manager quote character, if it is used in an ACB value then the whole value should be placed within another quote character, for example "AC????".
The override_acbname may also contain the special character '%' (percent symbol) in any number of positions in order to substitute characters from the userid.
