Okay.  PC LW is a 32-bit program.  Where did you hear otherwise?

I stand corrected  (todd)

Bill Gates didn't invent thunks, although Windows certainly uses them.
Windows programs explicitly create thunks with MakeProcInstance() when
installing callbacks, usually for window procedures.  This is just a
layer of indirection that allows programs to move around in memory.
It's not a Satanic plot.

sure. didn;t say it was. it was while working with win95 and nt that I
first heard of thunks. I thought it was a gates thing, but I guess I'm
wrong. reminded me of the "granules" term that Randy Cook (inventor
of the TRS-DOS operating system) applied to 5120 bytes of disk area! -todd
