You have to put it on a module, example:

#BEGIN OF masm.jam

import generators ;

generators.override masm.compile.asm : gcc.compile.asm ;

actions compile.asm
{
        ml "$(>)" -o "$(<)"
}

#END OF masm.jam

then at your Jamroot/Jamfile add:

import masm ;

masm.jam must be next to your project Jamroot
