chr_show_store(+Mod)

Prints all suspended constraints of module Mod to the standard output. This predicate is automatically called by the SWI-Prolog top level at the end of each query for every CHR module currently loaded. The Prolog flag chr_toplevel_show_store controls whether the top level shows the constraint stores. The value true enables it. Any other value disables it.
