 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.
 4    0000
 5    0000                  ; this example has been reworked to conform to updated lua5.4 and only official
 6    0000                  ; documented Lua bindings, the `sj.insert_label` has no more the optional arguments
 7    0000                  ; that said, you can use instead the regular asm syntax and `_pl` binding to create
 8    0000                  ; any kind of special flavour of label (DEFL, EQU, global, local, ...)
 9    0000
10    0000                  ; The extra options of `sj.insert_label` were promised to stay in v1.x
11    0000                  ; in the original test code, unless there is serious reason. Upgrade
12    0000                  ; to lua 5.4 is actually *that* serious reason, sorry.
