Modell! TRSDOS
AGAIN
Repeat Last Command
This command tells
TRSDOS
to re-execute the most recently entered
command.
AGAIN
cannot be used after certain library commands, utilities and user programs.
Example
T I l'1E:~
AGAIN
TRSDOS
will re-execute the
TIME
command.
Sample Use
AGAIN
is useful after
TRSDOS
has returned an Input/Output error message
instead of obeying a command. For example, suppose you type:
~\
I l..L. OLDF I l..E
=
1
and the diskette in drive 1 is write protected. Then you'll get an
ERROR
15
message. Put a write-enable tab on the diskette and type:
I\GAI N
Now TRSDOS will re-execute the command.
Suppose you are making multiple backup copies of a file from drive 0 to drive
1. Enter the
COpy
command once; for second and third copies, use
AGAIN.
For example:
COPY DAYSWORK=0 TO DAYSWORK=l
copies the file to a drive 1 diskette. Now put another diskette into drive 1 and
type:
AGAIN
to repeat the copy using the new diskette.
