Off the top of my head, I can think of two ways:

1) The STR_SEP method where the degree symbol, ï¿½, is the separator. The
first element of the result is then just the number in string form. By
using FLOAT, you'll have a real number. (However, I don't know how to
represent the symbol ï¿½ in the command....ASCII escape sequence or
something like that?)

2) Lopping off the last two characters manually, e.g.:

c_lat = "43.92ï¿½S"
len = STRLEN( STRTRIM( c_lat, 2 ) ) ; Make sure there are no " " at
the end
c_lat = STRMID( c_lat, 0, len - 2 )
lat = FLOAT( c_lat )

I do this sort of thing all the time reading in radiosonde data

good luck
