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 still shows extra options of `sj.insert_label`, which are not shown in
6 0000 ; official documentation. I'm not sure if these will stay for v2.x, so I'm
7 0000 ; not adding them to docs, but you can learn about any hidden optional arguments
8 0000 ; in sjasm/lua_sjasm.cpp file, tracking down the particular lua stub, and checking
9 0000 ; how many arguments and types are parsed, and how they are used in the call
10 0000 ; of internal sjasm function.
11 0000 ; These are to stay in v1.x forever like this, unless there will be really serious
12 0000 ; reason to modify them. For v2.x the main goal is to mostly keep them and make
13 0000 ; them official, but som pruning/reorganization may happen, plus newer Lua version..
