Unfortunately I dont understand this at ALL  :(  so sorry, I did try!!.
 Let me give you an example and see if you could help me more if its
not too much trouble.  The machine now accepts programs written just
like this...and this is ALL that it accepts
1,amps,50
1,timer,100
1,hon
LETS CALL THAT FILE "C.TXT"

that sets the amps to 50, for 100 seconds, then turns the machine on
(where it starts the timer itself)

what Id need to do (and if you can work with that example it would be
great), is make it run this program FIRST
1,amps,0
1,timer,5
1,hon
LETS CALL THIS "A.TXT"

which would not run any power through it for 5 seconds...THEN run the
above program ...so basically I would need the timer program that youd
help me with to send A.TXT and then wait 5 seconds and send C.txt.  Is
this possible?  does it make any sense?
Thanks so much in advance
Scott
