The DIRCMD variable is used by some versions of CMD to hold default options for the DIR command. TCC-RT does not directly support this variable, i.e, its value has no affect on internal commands. In general, it is more efficient to define several aliases, each including a different combination of options. For example, if you want the DIR command to default to a 2-column display with a vertical sort and a pause at the end of each page, you could use this alias:

 

alias DIR=`*dir /2 /p /v`I

 

If you wish to use or create a DIRCMD variable for compatibility with CMD, you can define the alias to append the contents of that variable to the DIR command:

 

alias DIR=`*dir %dircmd`

 

Now each time the DIR  alias is executed, the current value of DIRCMD will modify the execution of the DIR command.
