//Context: Most client side code.
 
//Ways to generate messages from client side code:
//Use the alert() function to show a prominent and blocking modal dialog which must be explicitly dismissed for execution to continue.
//Display a message to the user from Client code using g_form.addInfoMessage() or g_form.addErrorMessage()
//Use g_form.addDecoration() to show a small graphic symbol by a form field label.  A mouse-over popup hint may be included, and a color may be specified.
//Use g_form.flash() to display a flashing colored background box behind a form field label.
//Use the confirm() function to display a modal popup dialog to get a response (OK or Cancel) from the user before continuing execution.
//Use the jslog() function to write a message to the web browser console.

//Use the addParam() function, and by convention, the parameter named "sysparm_name" to specify which server side function to invoke.
//Additional arbitrary parameters may also be specified with addParam(); In this example "sysparm_Prefix".
