Yep. What I do is:
if (gpsdata.set & MODE_SET) {
switch (gpsdata.fix.mode) {
...
case MODE_2D:
if ((gpsdata.set & LATLON_SET)) {
formatLat (gpsdata.fix.latitude);
formatLong (gpsdata.fix.longitude);
...
case MODE_3D:
if ((gpsdata.set & (LATLON_SET|ALTITUDE_SET))) {
formatLat (gpsdata.fix.latitude);
formatLong (gpsdata.fix.longitude);
...
