Do auto-assembler scripts support define-like macros?

I'm looking for something similar to
Code:
#define something(param1, param2)
in C

For example, to push an integer value onto the FPU stack, you need code that looks something like this:

Code:
push 1500
fild [esp]
add esp, 4


I've been copying+pasting that a lot. It would be nice to be able to just write something like

Code:
PUSH_FPU(1500)

You can use define(name,whatever) to replace "name" with "whatever". You can't pass parameters to it AFAIK, so you'll still have to push it onto the stack.
Also, in CE, you can specify you're declaring an imm32 as a float by writing (float) before the number, so you can easily use fld instead of fild.

Example:
Code:
define(MOVE_FPU,db D9 04 24 83 C4 04) // fld dword ptr [esp] ; add esp,4

newmem:
  ...
  push (float)1500
  MOVE_FPU
  ...

Well that's... disappointing. Most other assemblers support macros - why doesn't CE use one of them to compile its scripts?

Not exactly clean... but it works!
Code:
{$lua}
local macro=[[
  push 1500
  fild [esp]
  add esp,4
]]
{$asm}

[ENABLE]
alloc(newmem,$1000)
newmem:
{$lua}
return macro
{$asm}
registersymbol(newmem)

[DISABLE]
dealloc(newmem)
unregistersymbol(newmem)
