One basic way I've thought to do this is to simply use the elevation data
in the populated place file. Instead of "MOUNT VERNON MD" I'd like it to
say "Mount Vernon, 90" So far I've got:
proper(left(name, len(name)-3) + ", " + string(elevation) )
I need to figure out if elevation is null. Not sure how to do that.
For now, I'm getting "Mount Vernon," for those population places that
don't have Elevation data, including the extra comma.
In some other software a function such as IsNull(field)
I checked Larry's nice function chart at
http://www.directionsmag.com/tools/Default.asp?a=alltools&ProductID=39
and didn't see a null function.
This is really two problems: how to take out the comma if elevation is
empty or null, And the totally different question of how to do a better
job of showing elevaton.
