(default is a compiler intrinsics that returns a 0 value of the type
you passed in, e.g. Nil for classes, '' for strings, 0 for ordinals and
for records all fields are set to 0)<br>

Thanks for your help.<br>

Are the above info. available anywhere in FPC's web site that I
overlooked? If not, maybe it should be added to its wiki.<br>
