*print-startup-message*

The value of this variable should be a (possibly empty) alist with elements of the form (type . brief). type should be one of the choices given in the description of print-startup-info or t (indicating all information should be printed). brief should be a boolean specifying whether long (value nil) or short (value t) information should be printed on a particular topic.

Among the values for type given in the description of print-startup-info are :compiler-optimization, :compiler-switches, and :case-mode. So if the value of this variable is the list

((:compiler-optimization . t) (:compiler-switches . nil) 
 (:case-mode t))

brief (t means brief) information on compiler optimization will be printed along with long (nil means not brief) information on compiler switches and brief information on the current case mode. (See Allegro CL Executables in startup.htm for discussion of the various case modes in pre-built images.)

Again, if type is t, information is printed on all topics. So if the value of this variable is ((t . t)), brief information will be printed on all available topics and if it is ((t . nil)), long information will be printed on all topics.

If the value of this variable is nil, no start-up information is printed.

The system examines this variable when Lisp starts up and prints the requested information just after the banner (i.e. copyright notice, etc.) is printed. You may wish to change the information printed. The change to the value of this variable can be made in the custom.cl file and the change will be seen in newly-built images. You can also set this variable with a command-line argument or in an init file, as both are processed in the startup sequence before startup messages are printed.

See also startup.htm for general information on starting Allegro CL, including information on command-line arguments and init files. The start-up messsage is described in the section The start-up message in that document.
