The main system error handler.

=== Inputs ===
* ([[83Plus:RAM:86DD|errNo]]) = error code

=== Outputs ===
* None

=== Destroys ===
* Everything (this routine does not return)

== Comments ==
This is the default system error handler, which will handle errors if no other error handler has been set. It simply resets the hardware stack, loads the "cxError" context, and jumps to [[83Plus:BCALLs:401E|Mon]].

Programs should never call or jump to this routine; I have no idea why it's a B_CALL at all. If you want to raise a system error, use [[83Plus:BCALLs:44D7|JError]], [[83Plus:BCALLs:4000|JErrorNo]], or one of the specialized error routines.

-This routine is sometimes used by the OS as an error handler.  It's very similar to [[83Plus:83Plus:BCALLs:4048|monErrHand]], and I'm not sure why  this routine would ever be used instead.

 Unlike monErrHand, this routine begins by resetting the hardware stack (but does ''not'' reset the FPS, OPS, or errSP.)  It then loads the "cxError" context, and jumps to [[83Plus:BCALLs:401E|Mon]].
