(BEGIN RESOURCES) VMDEBUG

% We keep track of (global) instances with another entry in the resource
% dictionary, an .Instances dictionary.  For categories with implicit
% instances, the values in .Instances are the same as the keys;
% for other categories, the values are [instance status size].

% Note that the dictionary that defines a resource category is stored
% in global VM.  The PostScript manual says that each category must
% manage global and local instances separately.  However, objects in
% global VM other than systemdict can't reference objects in local VM.
% This means that the resource category dictionary, which would otherwise be
% the obvious place to keep track of the instances, can't be used to keep
% track of local instances.  Instead, we define a dictionary in local VM
% called localinstancedict, in which the key is the category name and
% the value is the analogue of .Instances for local instances.

% We don't currently implement automatic resource unloading.
% When and if we do, it should be hooked to the garbage collector.
% However, Ed Taft of Adobe says their interpreters don't implement this
% either, so we aren't going to worry about it for a while.

%			<key> ResourceStatus false
%		ResourceForAll
%			<template> <proc> <scratch> ResourceForAll -
%		*ResourceFileName
%			<key> <scratch> ResourceFileName <filename>
%	Additional, specific to our implementation:
%		.Instances (dictionary)
%		.LocalInstances
%			- .LocalInstances <dict>
%		.GetInstance
%			<key> .GetInstance <instance> -true-
%			<key> .GetInstance -false-

%		.DoLoadResource
%			<key> .DoLoadResource <key> (may give an error)
%		.LoadResource

% .findcategory and .resourceexec are only called from within the
% implementation of the resource 'operators', so they don't have to worry
% about cleaning up the stack if they fail (the interpreter's stack
% protection machinery for pseudo-operators takes care of this).
% Note that all places that look up categories must use .findcategory

% The Category resource signals /undefined rather than /undefinedresource,
