necessary on client sideedit display $editmode

Displaymode can be achieved in DSPs only by use of non editable widgets

$formtitle Headers in HTML or in Uniface fieldsmessage WebmessageApexit exit (0) do not leave with negative statusaskmess Separate Dialog (DSP or JavaScript) with buttons

for the answer$curhits No stepped hitlist in web$fieldcheck No option to force validation with $fieldcheck If

immediate reaction is neccessary best check for change in Javascript

$instanceparent Function works also in DSPs but sequence of activation and perhaps DSPs itself different from CS

$batch DSPs canlsquot run in batch Forms can be kept for batch usage
