Ah, the file wasn't opened successfully, so f was null.
I really should be more careful about these things!

What is wrong with the following Lua function? This is taken from
"scite_other.lua" by Steve Donovan. I marked the error line in the
code below. The error message is:
attempt to index local `f' (a nil value)
function Perform(verb,arg,other)
local f = io.open(TEMP_FILE_IN,'w')
if not arg then
arg = ''
else
-- exec is a special verb _not_ handled by the Director interface,
-- which otherwise requires its input to be slashified.
if verb ~= 'exec' then
arg = string.gsub(arg,'\\','\\\\')
end
end
local cmd = 1
if other then cmd = 0 end
f:write(verb,':',arg,'\n')
f:write(cmd,' ',our_window,'\n')
f:close()
fn()
f = io.open(TEMP_FILE_OUT,'r')
local n = f:read('*n') -- < error here
f:read()
if n == 1 then
our_window = f:read()
end
end
