In teh above example, i made simiar to alias - dira to be executed as dir /A, only thing is you will have to use it with percentages.. as in %dira%

/ilan
Using the "set" command is not, in my opinion, a very efficient way for an alias to be created or used. Simply because of the way it needs to be typed on the command line or in a script. Also you can't use arguments with it.

Code:
C:> set dira="chdir /D $1"

C:> %dira% "C:\Documents and Settings\All Users"

The above command will not work. It would work if you only used the command with no argument capture but what would be the point? The whole idea of an alias is to be able to create a command with options and arguments without having to type the entire command every time you want to use it. In these examples we are using "dira." I count 4 characters. To use the "set" method you would be typing 6 characters to produce the same command if you were to use DosKey to produce the alias.

Code:
C:> set dira=chdir /D

C:> %dira% "C:\Documents and Settings\All Users"

The "set" command, in my opinion, should only be used to store variables.
