geeta,<div><br></div><div>Yes, you can write this output (result of 'd gr2stn....' using gxout print) to a file, but you did not say what type of output. A simple way to output to a text file, for example:</div><div>
<div>outfile='c:/temp/tmpprs.dat'</div><div>'set t 1';'set x 1';'set y 1'</div><div>'set gxout print'</div><div>'set prnopts %0.2f'</div><div>ts=1</div><div>while(ts<=10)</div>
<div> 'd gr2stn(TMPprs(t='ts'),77.5,12.5)'</div><div> tmp=sublin(result,3)</div><div> rc=write(outfile,ts','tmp)</div><div> ts=ts+1</div><div>endwhile</div><div>rc=close(outfile)</div><div><br>
</div><div>Above should produce a file (.../tmpprs.dat, in this case) with an output similar to this, where first value is the timestep, and second value is the interpolated value for that timestep:</div><div><div><div>1,308.80</div>
<div>2,311.90</div><div>3,311.30</div><div>4,307.60</div><div>5,303.90</div><div>6,301.30</div><div>7,300.50</div><div>8,302.90</div><div>9,308.20</div><div>10,311.50</div><div><br></div></div><div><br></div></div></div><div>
<div>You may also find this OpenGrADS Cookbook reference useful, depending on the type of output you want:</div><div><a href="http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file">http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file</a></div>

Dear Stephen, <br>Thank you very much for all the help. <br>It is plotting and also printing the TMPprs. <br>Can I write this output to a file?<br>I tried with fwrite but this does not seem to work. <br>Kindly suggest. <br>
