[Closed] Finding and Replacing text in a text file

hey guys,

I recently discovered, on this forum, a way to have multiple floaters using the same script without creating a conflict. It basically has a rollout in a text file, and the script replaces the name, title, and other data in the text file with an unique string, then runs the it.

On Console pressed do
		(
		local FSin = Openfile ((GetDir(#scripts))+"\\SyRGB\\Data\\CapConsole.ms") mode:"r"
		local FSOut = Openfile ((GetDir(#scripts))+"\\SyRGB\\Data\\CapConsoleTemp.ms") mode:"w"
		local tnRollName = ""
		local tnLine
		 do
		 (
				tnLine = readLine FSin
				if
				(
					matchpattern tnLine pattern:"*rollout_*"
				) 
				then
				(
					   if 
					(
						tnRollName == "" 
					)
					then
					(
						Local RollExists = false
						   local RollCount = 0
						   tnRollName = (filterString tnLine " ")[2] 
						   do
						(
							   RollCount += 1
							   RollExists = execute ( "( Classof " + tnRollName + ( RollCount as string ) + " == RolloutClass )" )
							   if 
							( 
								RollExists 
							)
							then  
							   (
								   local Rollopen = execute ( tnRollName + ( RollCount as string ) + ".open" )
								   if 
								( 
									not Rollopen
								) 
								then 
								   (	
									   execute ( tnRollName + ( RollCount as string ) + "=undefined" )
									   RollExists = false
								   )
							   )
						   )
						while
						(
							RollExists
						)
					   )
					tnLine2 = replace tnLine ( findString tnLine "rollout_" ) 8 ("rollout_"+ ( RollCount as string ))
				   )
				 format "%
" tnLine to:FSOut
			)
			   while
			(
				not eof FSin
			)
			   close FSin
			close FSOut
			   filein ((GetDir(#scripts))+"\\SyRGB\\Data\\CapConsoleTemp.ms")
			   deleteFile ((GetDir(#scripts))+"\\SyRGB\\Data\\CapConsoleTemp.ms")
		)

I’ll be honest, I don’t really understand what its doing, but its working.
The problem is I want to throw a wrench into the works by replacing another string in the original text file with a predetermined variable. I’m not sure how to make max find the string in the original file that i want to replace. Nor am I sure where in the script such an action would belong. The string that I need to replace occurs only once. FindString isn’t working.

any ideas guys?
