:CP/M Line Editing and Output Control
The following are the line editing functions supported by CP/M --
rubout Delete and echo the last character typed at the
console.
Ctrl-È   Deletå  thå  lasô  characteò  typed»   Backspacå  onå �
character; CRT-oriented
Ctrl-U Delete the entire line typed at the console.
Ctrl-Ø Deletå thå entirå linå typeä aô thå console»  Backspacå �
tï thå beginninç oæ thå currenô line; CRT-oriented.
Ctrl-R Retype current command line: types a "clean line"
following character deletion with rubouts.
Ctrl-E Physical end of line: carriage is returned, but
line is not sent until the carriage return key is
depressed.
Ctrl-M Terminates input (carriage return).
Ctrl-J Terminates current input (line feed); CRT-oriented
Ctrl-C CP/M system reboot (warm start).
Ctrl-Z End input from the console (used in PIP and ED).
Other control functions affect console output --
Ctrl-P Copy all subsequent console output to the currently-
assigned list device (LST:). Output is sent to both
the list device and the console device until the next
Ctrl-P is typed.
Ctrl-S Stop the console output temporarily. Program execution
and output continue when the next character is typed
at the console. Typing Ctrl-C returns control to CP/M.
Inpuô lineó caî generallù bå uð tï 25µ characteró iî length® Theù arå �
