filename.tcl-stack

keeps a record of all commands issued from TCL.

Normally, the item-id of the 'tcl-stack' file is the 'users' id. If a T option is included in the options attribute of the users item, the item-id of the tcl-stack is the line number of the process logged on. This option is available on 6.2 releases and higher.

A 'users item' must be created in the 'users' file prior to any user logging on to the system. However, 'tcl-stack' items are created automatically when the user executes the first command from TCL.

Each and every unique command typed in at the TCL prompt character (:) is saved as an attribute in the 'tcl-stack' file. Having unlimited item size means that there is no limit to size of the items in the tcl-stack. Therefore, the file size should be monitored by the System Administrator.

Because the 'tcl-stack' file is on the 'dm' account, it should be saved ('t-dumped') prior to an operating system upgrade.
