Entering Input in While loop

How do you input data using read() when your in a while loop.

term.clear()
term.setCursorPos(1,1)
print("Enter Command:")
local password = read()
while true do
   if password == "Engage Terminal" then
	  rs.setBundledOutput("bottom", colors.combine(rs.getBundledOutput("bottom"), colors.white))
	  read()
   elseif password == "Engage Code Room" then
	  rs.setBundledOutput("bottom", colors.combine(rs.getBundledOutput("bottom"), colors.orange))
	  read()
   elseif password == "Disengage All" then
	  rs.setBundledOutput("bottom", colors.subtract(rs.getBundledOutput("bottom"), colors.white, colors.orange))
	  read()
   elseif password == "Shutdown" then
	  break
   end
end

This is what I tried using but only the first line I enter after starting the program does something. For instance I can type in "Engage Code Room" and only the set of code under it will fire, anything else entered after that does nothing.

You were probably trying to do something like this:

term.clear()
term.setCursorPos(1,1)
while true do
    print("Enter Command:")
    local password = read()
    if password == "Engage Terminal" then
        rs.setBundledOutput("bottom", colors.combine(rs.getBundledOutput("bottom"), colors.white))
    elseif password == "Engage Code Room" then
        rs.setBundledOutput("bottom", colors.combine(rs.getBundledOutput("bottom"), colors.orange))
    elseif password == "Disengage All" then
        rs.setBundledOutput("bottom", colors.subtract(rs.getBundledOutput("bottom"), colors.white, colors.orange))
    elseif password == "Shutdown" then
        break
    end
end

Notice how in Lyqyd's version, the call to read() is inside the loop, so it runs every time the loop runs.
In your version, it's outside the loop, so it runs once before your program enters the loop.
