/**********************************************************************
 chkMandatory: check mandatory fields on the form objForm
 parameters: objForm - form reference

 pre-requisites:
    aMandatory - array of fields for which mandatory evaluation should be done
    Depends on:   alltrim() which is a function of string.js library

    aMandatory should be defined on each HTML page format of aMandatory:
    aMandatory[<field-name-string>] = new Array(<message-string>, <input-type-string>, <focus-on-string>);

 <message-string>: message to be displayed on mandatory check failure
    (NOTE: system dispalyes "<message-string> is mandatory")
 <input-type-string>: "TEXT", "RADIO"
 <focus-on-string>: name of the field where focus should be placed on mandatory check failure.
        if this is "" then focus is place on <field-name-string>
	
 chkMandatory function was revised and rename on 8-1-2005. JT
