[Vm-dev] Need a marker primitive

[Eliot Miranda]

Hi Tim,

    in what context do you want to notice something is about to fail?  Simulator, real VM under gdb or what?  And when?  Primitive failure in the Cog VM is the writing of a non-zero value to primFailCode.  That can be done with a conditional breakpoint.  I'm not sure what you mean.  Can you be more precise?

TIA
