This command executes the LAN-specific SDA extension image which is
a collection of LAN-specific commands which mirror some of the display
functions of SYS$SYSTEM:LANCP.EXE in SDA.
By default this image is loaded from SYS$SHARE. However, it can
be redirected with the following logical:
$ define lan$sda [dir-spec]lan$sda.exe
