[daip] UVFLG elevation

[Leonia Kogan]

Lynn,
Lynn,

Did you used UVPLT to see elevation(time?
I have tryed UVFLG with different ranges of elevation and including your 
strange FLAGVER=99, with selection of source and source= '', with opcode 
='flag' and ''.....
By the way I do not understand why UVFLG getting FLAGVER=99,
prints out "Nothing was added to FG table   4" ?

Everything works with my data which are compressed although it is not a 
matter I think. :(
Can you try UVFLG with source =''? and with bigger range of elevations
to flag
It may help you/me to get a clue

Can you send me imh of your data?

Thanks

Leonia
