[ncl-talk] convert string to fortran character

[Zhifeng Yang]

Hi Dennis and Rick,
I found tochar will give me an array with 2 dimensions. Now I can use the
following to get what I want
times = f->Times
times_tmp = tochar(tostring(5))
times(0,3) = times_tmp(0)

then it works. Thank you for your help.

Best,
Zhifeng
