RedPower bundled pulser

Is there a way to read an input an them pulse redpowers bundled cable the number of times the input

print(" How Many?")
input = read()
a = input * 5
b = input
print("Gold On The Way")
rs.setBundledOutput("back".colors.red)

Its The last line that needs to be replaced i think

Firstly you have to of course make sure that it works. Which it might, depending on the mods you have installed. And then you're going to need a loop. For your loop you're going to need a for loop and your "b" variable doesn't need to exist.

for q = 1, a do --# Starting at 1, with q being a new variable, and ending at a, increment by 1
  rs.setBundledOutput("back",colors.red) --#You had a period, needed a comma between back and colors
  sleep(0)--#Make it wait a second
  rs.setBundledOutput("back",0) --#Turn off all bundled output.
  sleep(0) --#Really it waits a game tick.
end

This loops through the code until q == a and once it does, it doesn't run through anymore

A couple of things, better to use tonumber() to convert read()'s output to an actual number. Generally read() returns a string - while Lua will let you treat strings as numbers (sometimes), it's better to be specific. Eg:

input = tonumber(read())

sleep(0) won't be sufficient - that'll only pause for a twentieth of a second (the minimum pause allowed, which happens to be the same time period as one MineCraft tick), but redstone only updates every tenth of a second. If you try to change state faster than that then you won't be able to detect the pulse at the other end. Use sleep(0.1) or perhaps even a greater time period.
