Running gdal_merge.py

Hello,

I unziped the openev_fw_1.6.2.zip and made the required change
in the setfw.bat file.

I can run Openev and all the gdal utilities.
However, the gdal_merge.py module code opens in the MS Notepad
when I try to run it.  I see that the icon of the modules are associated
with the Notepad.

I do not know anything about Python.  I've heard of it but never
used it before.

What program do I need to associated the module with in order to
run it, or what is needed to do to run it on Win2k?

Any suggestion is welcomed!

Thanks,

Reinaldo
