Resident - Adds or Removes a command in memory
NAME, FILE, ALIAS/K, REMOVE/S, ADD/S, REPLACE/S, PURE=FORCE/S, SYSTEM/S,DEFER/S
NAME - Name of the resident to be added into the resident list FILE - Full path to the executable to add ALIAS - Add an Alias of an existing resident cmd instead of a new one REMOVE - Deactivates the specified internal command REPLACE - Default option ADD - Use this option to override REPLACEment and make several versions of a command resident simultaneously, use the ADD option, giving a different NAME for each version loaded. PURE - Forces Resident to load commands that are not marked as pure and use them to test the pureness of other commands and programs. Use the PURE option with caution. Be sure the programs that you make Resident meet the criteria to be resident or be careful to use the command in only one process at a time. SYSTEM - Add the specified command in the System portion of the list The command then becomes available as a system component and cannot be removed from the list DEFER - Command is loaded to RAM when it's used for the first time
Resident with no FILE argument will display the resident list. You can specify the SYSTEM argument to show only System components.
NOTE: To be made resident, a command should be pure, meaning that it is both re-entrant and re-executable. A re-entrant command can properly support independent use by two or more programs at the same time. A re-executable command does not have to be reloaded to be executed again. Commands that have these characteristics are called 'pure' and have the p (pure) protection bit set.
