<div>Sorry, i must correct something...</div>
<div> </div>
<div>The option of creating an environment variable works if you do not specify the path of the file in the command line. I said that didn't work but is not true. After some tests, i confirm that if you have set the variable to the correct path, and use the options +nadgrids=
myfile.gsb, PROJ makes the NTV2 transformation correctly.</div>
<div> </div>
<div>Sorry for the mistake. Now i must enquire how to fix an environment variable using ASP, and without administative privileges.</div>
<div>Any other ideas would be appreciated.</div>
<div>Thanks in advance for your help.<br><br> </div>

<div>I would like to point out that my question makes a lot of sense...</div>
<div>Frank, i am using a hosting service where every user has assigned a specified directory (for instance c:\users\...\...\user7771) and so we have no administrative privileges. In addition, we are using a server side scripting language to develop a guided interface to
PROJ.4, so i do not expect to be able to fix environment variables nor write on c:\proj directly.</div>
<div> </div>
<div>Anyway, on my servers, where i have all the administrative privileges, i've been carrying some tests according to your recommendations:</div>
<div> </div>
<div>- I tried to include in the command line the path to the gsb file: for instance +nadgrids=c:\proj\xnad\myfile.gsb (notice that i have introduced xnad instead of nad, and obviously renamed the nad folder to xnad previosly). The RESULT DOES NOT WORK. Testing with some coordinates didn't make the NTV2 datum shifting.
</div>
<div>- I also tried to set a new environment variable form the DOS prompt, with the sentence: set PROJ_LIB=C:\PROJ\XNAD. Afterwards, and also from the DOS prompt, the sentence SET reports the successful creation of the variable pointing at the specified path. In spite of all of this, the RESULT DOES NOT WORK. Testing again with some coordinates, didn't make the NTV2 datum shifting.
</div>
<div> </div>
<div>Any other idea? If the first option would work (to introduce the path of the gsb file in the command line of cs2cs) it would be fine for me, because i am using a shell to execute command line sentences through a server side scripting languaje.
</div>
<div> </div>
<div>Thanks to both of you for your attention and responses.</div>
