[gradsusr] Sprintf to write binary to ascii

[Zablone Owiti]

Hi Zilore, 
I know fprintf (and NOT Sprintf) used to write out binary data to ascii format. Depending on your requirement, you can use it to write out the whole data (lets say gridded binary data) and also write out the corresponding latitudes and longitudes on separate files. This procedure is demonstrated in the following link:http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file

You can also use it to write out data averaged over a particular domain or grid box as in the example of a .CTL file below:

'sdfopen H:/griddata/data.cdf'
'set lon 10'
'set lat 15'
'set t 1 516'
'define pc2sst = aave(sst,lon=-165,lon=-80,lat=-5,lat=5)'
'set t 1 516'
'fprintf rain raingcpc.txt %g 12 1'

NB: In the last line, rain is the variable, raingcpc.txt is the outputfilename, 12 is the number of values in each line (i.e monthly data in this case so that each line is Jan to Dec for each year), and 1 is the number of spaces between the values in each row/ line.

Hope this will help
