LISTREDO
Displays one or more commands in the command history buffer.
Syntax
[;ABS]
LISTR[EDO] [m] [,n] [;REL]
[;UNN]
Parameters
m,n displays a range of commands in the command
history buffer. m is the starting number (least
recent) and n is the ending number (most recent).
If m is equal to n, only the specified command is
displayed. m and n can either be absolute
(positive) numbers or relative (negative) numbers;
however, both must be either relative or absolute.
The use of these parameters is discussed further
in the table below.

ABS displays the absolute command numbers. ABS is the
default. Absolute numbers are positive numbers
beginning with the first (least recent) command in
the command history buffer. For example, 1 is the
first command in the command history buffer.
REL displays the relative command numbers. Relative
numbers are negative numbers beginning with the
last (most recent) command in the command history
buffer. For example, -1 is the last command in
the command history buffer.
UNN suppresses command numbering.
Discussion
The LISTREDO commands displays the commands from least recent to most
recent. Up to 20 commands can be displayed. The LISTREDO command is
added to the command history buffer.
Example
In this example, the first LISTREDO command is issued when the command
history buffer contains two commands. However, when the buffer is
displayed, three commands are listed since the LISTREDO command is added
to the buffer. The next LISTREDO command lists all the commands in the
commands history buffer with relative numbers. Finally, the third
LISTREDO command lists the third most recent command through the most
recent command with relative numbers.
