Railcraft control program not finding redpulse/redprobe

http://pastebin.com/MFGm9mGU

This is my code to control a multiple location railway across the server (multiplayer). When I run this program, the list prints correctly, the input is received, but at the point of the redpulse and redprobe lines (line 43 and following), I get only "No such program". I put in the print(shell.path) of both programs and this latest iteration has me directing the path from root to the programs.

I've tried copying the programs to the root directory with the railrun program, putting in the directory path to the programs, loading the program in the programs directory (this failed multiple times). Does anyone have any suggestions?

Please post the code into a code box on the forums rather than linking to a pastebin.

Why do you have extraneous punctuation in your program paths? It should simply be "/rom/programs/redpulse" without periods or colons.

   repeat
	  if east then while not returneast do
		 probe = shell.run("/rom/programs/bin/redprobe")
		 if (probe == "back = 1 (white)") then returneast = true
		 end
	  end
	  if west then while not returnwest do
		 probe = shell.run("/rom/programs/bin/redprobe")
		 if (probe == "back = 32768 (black)") then returnwest = true
		 end

   end
   end

end

Removed and still "No such program."

You shouldn't need any of the paths unless you've changed the default path setup or had an installation issue.
The problem is the way you're sending your args. They need to be separated by commas. It thinks yoiu are trying to run a program named "/rom/programs/bin/redpulse top 1 0.5".

shell.run("redpulse","top",1,0.5)

Ok, I did all that (removing the paths and extra punctuation and put in the commas and quotes) and it worked. Thank you.
