// ENTRY VALIDATION & FORMATTING

// 11/10/97 - TJS Added functions
// 01/21/99 - SCC Added function isUniqueItem
// 02/11/99 - TJS Tweaked number formatting functions
// 03/11/99 - SCC Added param to validateNum; boolean to accept 'none' and change to zero
//*****
// 06/06/99 - SCC - Ported from Pro WAPP. ONLY called by mtg_calc.html.
