[RegCNET] questions about rcm2rgrid

[Siraj Ul Islam]

Hi Moet,

thanks for your comments. Well I have modify the script as you have
suggested. Now the rcm2grid funtion is working but the errors comes
from the line 56( ; ####ERROR LINE)  now where the output RT_re.nc
file is written. I am sending you the error as well as the modified
script with NC dump of HEAD_OUT and SRF files.
Hope you will again help me to solve this problem.

cheers
