Hmm, calc-tile.pl seems to do about the same as my fgbucket.cpp. A little more verbose, and I swapped the input args so I can paste straight from airnav.com... How are you using telnet.pl to get altitudes? Thanks, Ron ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
