Execute the batch file by entering its filename, followed by the
drive and program name. For example, to change to the correct
directory for Myprog, type:
progdir B: myprog
I
ENTER
I
The batch file substitutes B: for %1, making Drive B your cur-
rent drive. Then it substitutes Myprog for %2. It goes to label
:W and changes the directory to \ USER\MYPROG. Then it
goes to :Z. The line following :Z causes CHDIR to display the
current directory to verify that it is correct.
