hello again, you may use the VSIO* sys vara
if you wish, you may create a file with those coordinates ( so to inspect the file only once and see 999+ values, rather then checking frequently the common variable; if this is will help you, then you will have much more time for beer, or whatever ... beer+whatever )
please, why do you need this ? kindly
