Dear Friends
I am a new user of IDL. this time I am trying to read the data of this
type.
GRCOF2 0 0 0.100000000000E+01 0.000000000000E+00 0.0000E+00
0.0000E+00 20030301.0000 20030401.0000 nnnn
GRCOF2 1 0 0.000000000000E+00 0.000000000000E+00 0.0000E+00
0.0000E+00 20030301.0000 20030401.0000 nnnn
GRCOF2 2 0 -.484169137464E-03 0.000000000000E+00 0.1256E-10
0.0000E+00 20030301.0000 20030401.0000 ynnn
It is a GRACE satellite data
But I am getting error which says "Unable to convert String to
Floating"
Can any one help me in reading it, cause i have 122 files with 1895
lines for each, using IDL will simplify it a lot for me. I will wait
for your golden responses

Right!
IDL> n="+2.64342987e+02"
IDL> Print, Double(Str_Replace(n, 'e', 'd')), Format='(F0.6)'
264.342987
Cheers,
David
