Our shop has a package of programs we would like to convert to OS X.x but we are having problems with GUI migration and, particularly, file handling. (We commonly have input file sets and outfile sets spanning over 100 GB. That's abunch of 2 GB files to handle.) Anybody know of a good OS X programmer who might give us a hand? Perhaps even a student who wants some extra cash? Thanks, List! Vard Nelson 713.874.1628 - Office vnelson at detectgeo.com
