Ah, my pet peeve. I have two problems with much of the free
code out there.
1) Portability
I can't count the number of times I have tried to use free
code, but it won't work because the programmer put in some
platform-specific operations. At that point it is usually
easier to write my own code than try to hack the free stuff.
The main reason I switched over to IDL was for platform-
independent development. Otherwise I would have stayed with
FORTRAN-90.
2) Flexibility
Too often the free code will only work with:
a specific data format, or
a specific data size, or
a specific data type, or ...
Even some procedures supplied in the IDL library fail in this
area.
That is why I rarely use "free" code.
