Conditional statements - if, then, elseif

The if-then conditional statement evaluates an expression and executes a block of code if true:

   if status.body then     --Do something   end

Lua also supports an else-if conditional statement with the keyword elseif:

   if status.body then      --Do something   elseif     --Do something else   end

If-then statements must end with the terminator keyword end.
