OPATTR throws errors (jWasm v2.10, Apr 20 2013) for invalid register expression, whereas MASM returns zero:
%echo @CatStr(%(OPATTR WORD ptr eax))
%echo @CatStr(%(OPATTR REAL8 ptr xmm0))
All over it seems like that MASM accepts nearly everything, as long as there are no invalid characters or unbalanced brackets in the expression.
