You need to either:
- Find where the perldl executable was installed and put its location in your path.
- Make a batch file that runs perldl using its full path and put it in a location containing other executables, such as the windows/system directory.
- Type the full path to perldl when you run it.
You may get better suggestions from someone who has actually run PDL on Windows (I haven't) but I thought I'd make an attempt at an answer. The
PDL Mailing List will likely be a good source for answers to this and other questions.
Glad to see people using PDL! :)
