 1    0000                  ; test the new way of lua `_c`/`sj.calc` function to do the define/macro_arg
 2    0000                  ; substitution before the expression is evaluated, so using macro arguments
 3    0000                  ; inside lua script should be now trivial, no more workaround through DEFINE.

11    0000                  ; These are to stay in v1.x forever like this, unless there will be really serious
