MMX error

[RuiLoureiro]

Hi
    I am using MMX registers but when i assemble ASM file i get this:

Assembling: C:\MASM32\RCLLIB3\Cnv2.asm
C:\MASM32\RCLLIB3\Cnv2.asm(648) : error A2006: undefined symbol : mm0
C:\MASM32\RCLLIB3\Cnv2.asm(649) : error A2006: undefined symbol : mm1
C:\MASM32\RCLLIB3\Cnv2.asm(650) : error A2006: undefined symbol : mm2
C:\MASM32\RCLLIB3\Cnv2.asm(651) : error A2006: undefined symbol : mm3

C:\MASM32\RCLLIB3\Cnv2.asm(703) : error A2006: undefined symbol : mm3

The Cnv2 file begin with this:
;====================================

    .686
   .mmx   
    .model flat, stdcall            ; memory model & calling convention
    option casemap :none      ; case sensitive

    Solved:

   .686
   .model flat, stdcall            ; memory model & calling convention
    option casemap :none      ; case sensitive
   .mmx

place the .mmx (and .xmm) directive(s) below option casemap:none - i had some problems with this because i placed .mmx and .xmm above option casemap.
