Dear all,

  In the document http://www.digitalmars.com/d/iasm.html, section "Operand
Types" does not contain the keyword "qword ptr".
  This keyword is required even for 32bit machines. Some MMX instructions take
arguments of this type!
  Did I miss something?


Best,
Tiago

I always found qword ptr confusing. You can use "long ptr" or "double ptr" 
depending on what is needed.

BTW: On that page, "Operand types" still contains a reference to 
"extended ptr". This was changed in the compiler a long time ago. Spec 
should read "real ptr".

The only surviving trace of the old name "extended" is in the "de" 
pseudo-op. I wonder if it should be "dr"? I think that "de" is 
non-standard anyway, it is "dt" (stupid name) on most assemblers I've used.

Please note that in the same document "long ptr" is not mentioned - the HTML
doc needs to be updated!
