    Why don't you have any stack space for the new cog?

    i.e.

    VAR
 Long Stack[noparse][[/noparse]50]

    Bob,

    Assembly cogs don't use stack space.

    Thanks! Phil. I thought it may have been that but even after a year of Prop learning when I quickly look at code it's often confusing to know if it's Spin, Spin calling Asm, Asm, turn.gif I had to think it all through for a while before it finally made scense in that it's pure asm.
