"true" Pick arrays cannot be redimensioned, and put any excess into the last element (this presumably includes UV's "true pick" flavours). INFORMATION arrays can be redimensioned, have an element 0, and put any excess in there. Presumably the PI flavours of UV (and iirc IDEAL) do that. Note that even with a two-dimensional array, there is only one element 0, that has to be accessed as (0,0) (if one index is zero, the other one has to be, too) > > Brian Cheers, Wol > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On Behalf Of George Gallen > > Sent: 12 May 2005 16:01 > > To: u2-users@listserver.u2ug.org > > Subject: RE: [U2] I'm in an Array quandry, any suggestions... > > > > WOW.
