|Command||tcl.type-ahead Verb: Access/TCL
Applicable release versions: AP
|Description||enables or disables the system-wide type ahead feature, or displays the current status if no options are provided.
"Type ahead" is the process of buffering characters entered at a keyboard to allow for faster typing.
When type-ahead is "on", the system allows typing in characters "ahead" of their being displayed.
For example, after entering a "select" command at TCL, a "save-list" command can be entered into the type-ahead buffer. When the "select" finishes, the "save-list" command will be immediately entered provided a <return> was issued at the end of the command.
The command does not display on the screen until the previous process returns to TCL. There is no practical limit to the number of commands that can be "typed ahead", short of one's confidence in their abilities to type in the dark.
|Options||f Turns off type-ahead.
n Turns on type-ahead. This is the default.
s Suppresses output of status message.
