/* Error codes
 *
 * There are basically two types of error codes -- with each type
 * residing in a single word in a two word error code value. The lower
 * 32-bits contains an error class and code that represents exactly 
 * WHAT error occurred (e.g., non-numeric text in a numeric value 
 * entered by a user, bad virtual address, etc.). 
 * 
 * The upper 32-bits represents what type of data was being referenced 
 * when the error occurred (e.g., bad proc struct). Having two tiers of 
 * error codes makes it easier to generate useful and specific error 
 * messages. Note that is possible to have situations where one or the 
 * other type of error codes is not set. This is OK as long as at least 
 * one type s set.
