/*
 * mprintf () requires a message number for a stencil, and a message type
 *   from which to retrieve it.  The third argument, "fmt", is interpereted
 *   as being similar to printf... the following is its syntax:
 *      "[%[-][width]{[l]{x/d}/m/c}]*"
 * That is, the following string:
 *   %-ld%15m%d%lx%-20c
 * Tells mprintf to expect 5 replacable parameters:
 *   1: A left-justified integer double-word (long), 8 characters, decimal
 *   2: A right-justified message (which will be retreived), 15 characters
 *   3: A right-justified integer word (short), 8 characters, decimal
 *   4: A right-justified integer double-word (long), 8 characters, hex
 *   5: A left-justified character string, 20 characters
