It would be really nice if one could enable calling arguments by name using modeswitch ;-) http://www.freepascal.org/docs-html/prog/progsu106.html > PS: Please keep the fpc-devel list as recipent as well (either as main To or > as CC) so that others interested in this topic can read your messages as > well.
