"Recognition" input is another feature of the TOPS-20 operating system
that speeds up your input, by finishing the typing of a command or
command argument for you when you have given only part of it and then
prompting your next response.
As soon as you have typed enough of a command or argument to
distinguish it from others, press the ESC key: the system will finish
the word, if possible, and prompt your next input with guidewords
enclosed in parentheses. By pressing the ESC key without beginning an
argument you make the system print the default argument, if there is
one. If the system cannot help you, either because you have not typed
enough characters to make your intentions clear or because there is no
default, your terminal makes a warning noise - either a ringing bell
or high-pitched beep.
Because the ESC key does not produce a printed character, you may be
unable to remember exactly where you pressed it when later examining
the output from a hard-copy terminal. If you want to avoid this
possibility, use the TERMINAL NO RAISE command to make your terminal
produce lowercase input, to distinguish it from the uppercase printing
of the system.
For TOPS-20 Version 7, recognition has been expanded so that presssing
the ESC key also shows as much of a command keyword or file
specification as possible. For file specifications, recognition is in
effect only for the file name, extension, and version.
You cannot use recognition for device names or directory names
(including file structures), jobnames (for example, with the MODIFY or
CANCEL command) or logical names.
