Hi all,
I am trying to use IDL to read and write CDF files. Now I am suffering
a problem. I am trying to set my default working directory to "D:
\IDLWorkspace\". And I set "Reference->IDL->Path" and add the "D:
\IDLWorkspace" to the list and move it to the top. But it does not
work.
The reason why I want to set this directory is that otherwise every
time I am trying to read a file, I have to write the full path. By
setting a default working directory, I can just use
id=cdf_open('ge_edb3sec_mgf_20000125_v01.cdf')
instead of
id=cdf_open('C:\ge_edb3sec_mgf_20000125_v01.cdf'). I believe such a
small aim is achievable in such a powerful software like IDL. It is
just that I do not know how to do that.
This is just a simple example. My directory is much longer.
So as mentioned, I failed at setting the working directory. I hope
some one could help me.
Thanks in advance.
Sincerely,
Li, Tongmu

Check out FILE_WHICH. By default, it will check for files in !path.
