I cannot put my finger on sumnums - must have it somewhere, I
suppose. If it is meant to add up all the positive integers
occurring in a text then this ought to do as an unsophisticated
zero-approximation:

#! lua
local n = 0
for line in io.lines (arg[1]) do
  for x in line:gmatch "%d+" do n += tonumber (x) end -- for
end -- for
print "Total = ", n
