Subject: Function pcall and 0..n return values



Hi.

I'm having following problem with function pcall. I'm using function pcall
with different functions that have their parameters (0..n) in a table. I
found unpack-function very practical for parameters. The problem is that
functions may also return 0..n return values. How could I code a general
case that saves return values of pcall-fucntion for example in a table? I
cannot use unpack-function for table as second return value because it
causes a syntax error.

Example for using unpack-function for parameters in a table:
function Test(a, b)
  return a, b
end

local bStatus, a, b
local Param = {1, 2}

bStatus, a, b = pcall(Test, unpack(Param))
print(a, b)
