<div>I think you don't have the grid shift files that are required for</div>

<div>The files are called alaska and conus, and NTv2.gsb for</div>

<div>The US files can require an extra manual <span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.296875); -webkit-composition-fill-color: rgba(175, 192, 227, 0.230469); -webkit-composition-frame-color: rgba(77, 128, 180, 0.230469); ">command

<div dir="ltr">Thank you, I tried what you said, and what I'm getting as output is as follows when I run the same batch file:
<div><br>
</div>
<div>
<div>WGS84-NAD27</div>
<div>* * 0.000</div>
<div>WGS84-NAD27PAft</div>
<div>* * 0.000</div>
<div>NAD27-NAD27PAft</div>
<div>2502332.66 416669.38 0.000</div>
</div>

<div>I'm thinking my EPSG definitions might be messed up somehow... but I also tried copying from
<a href="http://spatialreference.org"></a><a href="http://spatialreference.org">spatialreference.org</a>, and still I get the same output. (It seems like the 4326 EPSG is not working... ) Any further ideas? Your second result is the correct and expected conversion
result... not sure why I'm getting asterisks and zeros for the same command! :/ Thanks again for your help!!</div>
