how to assign a NaN

[xvtstephen]

I am reading data with lots of missing values and need a good way to
be a ble to assign NaN to integer, real and character vars.

the missing value is represented by an empty string '' ! two quotes
without a space

I am using gfortran which has the isnan(x) to check for nan.

I hope there is a way to use a character representation of the NaN so
then

read(ch(1:2),*) myint,myreal

will give me int and real nans from the same string in ch(1:2)

thanks everybody.
