Sometimes it is useful to use macros to dress up some common elements in my code. For instance, back in nasm, I used several single line macros to define C strings, access stack, etc.

Code:

%define _csln(s) db s, 0xd, 0xa, 0
example:
msg_hello db _csln("Hello world!")

Another example is simplifying stack access:

Code:

%define stack(x) rbp - %[stkname] %+ _size + %[stkname] %+ . %+ x
example:
lea rdx, stack(v1)

Is there an equivalent to this in fasmg?[/code]

There is an inline macro add-on here: https://github.com/tgrysztar/fasmg/blob/master/packages/utility/inline.inc
