Keyaheads
TRSDOS allows keyaheads of up to 80 characters. This means you can type in the
next command while previous ones are being executed.

ready to interpret it.

first command:
DI R{SYS} (ENTER)
TIME (ENTER)
FREE (ENTER)
Press (BREAK) to interrupt the operation currently in progress; if a keyahead line is
available, TRSDOS will begin interpreting it. Press
(HOLD)
to pause the operation
currently in progress; press (HOLD) again to continue.
