We generally call them undocumented features.  :icon_mrgreen:

Hutch, these features are all documented now.

Nah, this is just propaganda from the competition.

What makes me laugh is MASM was always a bad mannered old pig, that's part of its charm. Its task is to screw mnemonics together, not to hold the hand of the timid. You learn its "features" the hard way like normal and manipulate them to do the task you want. Now the ancient macro engine is an even bigger old pig with notation that was out of date in 1988 but interestingly enough if you massage it hard enough, you get results.

:P

Still one of my favorites:

Code Select Expand

foo macro
echo did you see me?
EXITM <0>
endm

% ; foo()Undocumented feature "expand macro function and discard return value" 

[jj2007]

% ; foo()
Undocumented feature "expand macro function and discard return value" 

Similar (but quite useful):

include \masm32\include\masm32rt.inc

void MACRO args
  @CatStr(<;>, <args>)
ENDM

.code
start:
  void rv(MessageBox, 0, "Hello World", "It's all void:", MB_OK)

  exit
end start
