Thanx to all that responded telling me to use a .bat file.  Now a question:
Why does this only work in a batch file?  Also,  the SECOND substitution
I try fails (about 30% of the time).  I use the following addp.bat file:
   path=%PATH%;%1
Any explanations?   Please mail as I do not wish to tie up the net with
this any further...
