</div>
<div>the gl.i.j is a script variable(?) you'd have to 'print' it to a txt file and then convert to grads...</div>

<div dir="ltr">Hello,
<div><br>
I created a variable ("gl") that uses two for-loops and an if-else statement to determine areas that need to be masked. Here is a snippet of the code:</div>
<div><br>
</div>
<div>
<div> if (landuse = -80 | landuse = -104 | landuse = 37)</div>
<div> gl.i.j = 1</div>
<div> else</div>
<div> gl.i.j = -999000000</div>
<div> endif</div>
</div>
<div><br>
</div>
<div>Then I close that file and open a new file to apply the mask:</div>
<div><br>
</div>
<div>
<div>'close 1'</div>
<div>'open /data/SOOapps/mjb-apps/NDVI/ndviout.ctl'</div>
<div>'define maskrh900mb=maskout(rh900mb,gl)'</div>
</div>
<div><br>
</div>
<div>This is giving me the following error:</div>
<div><br>
</div>
<div>
<div>Syntax Error: Invalid Operand </div>
<div> 'gl' not a variable or function name</div>
<div>Operation Error: Error from maskout function</div>
<div> Error ocurred at column 1</div>
<div>DEFINE error: Invalid expression. </div>
</div>
<div><br>
</div>
<div>The two arrays (rh900mb & gl) are the same dimensions, so I'm not sure what is going wrong. Does anyone have any suggestions?</div>
<div><br>
Thank you,</div>
<div><br>
</div>
