Thanks. I was just looking for assurance that my IDL work was not in
vain.

"Why I use IDL" by Paul
IDL> myx=fltarr(100)
IDL> myy=fltarr(100)
IDL> openr,1,'mydata.binary'
IDL> readu,1,myx,myy
IDL> close,1
IDL> print, myx[0]
1.04215e-26
[paul: "Huh?"]
IDL> print, swap_endian(myx[0])
235.305
[paul: "That's better"]
IDL> plot, myx, myy
[paul: that was easy. look at my pretty data]
Generally, viewing long strings of numbers makes my eyeballs glaze over. The ability to
read and view my data in 30seconds makes me happy. :o)

Wouldn't you think that the time test has been passed by IDL? It has its
own clientelle that seems to be growing, not shrinking.
Besides, there is nothing in IDL or Java that can't be implemented in C,
Perl or Fortran for that matter. Speculation of this sort looks to me
like, would VW or Saab be able to hold its own in Toyota, GM and Ford
world. There are so many users with all sorts of tastes out there that
the answer is yes, I think.
Cheers,
Pavel

Please look at deja.com for recent threads on similar topics. There
has been ample discussion about this (although not specifically wrt
Java). In short: there are plenty of programs around that do some of
the things that IDL can do - some things better, some things worse,
some things faster, some things slower - but you have a very hard time
finding anything that does everything that IDL does at least as well.

I have over 15 years of IDL experience and have also done a limited
amount of Java over the past few years. IDL has an excellent base of
software you can tap into to do math, plotting, image manipulation, etc.
It's also easy to code GUIs once you get the hang of it. In IDL, I can sit
down with a text file full of data and have it plotted in a matter of
minutes. The last time I tried to do that in Java, I found the file I/O
very limited. Just reading in and parsing the data from the text file was a
pain.
We've also found IDL excellent for software prototyping. In a few
months we put together a GUI application that does a lot of file I/O, image
manipulation, and handling of user input via GUIs. It started out as
roughly 10,000 lines of code and we've been adding to it and tweaking it and
it's grown to roughly 20,000 lines of code. We've toyed with the idea of
porting this GUI application to Java, but have stayed with IDL since it has
all the functionality we need and has served us very well so far in the
development of this application. The IDL library really facilitates image
manipulation, equation solving, plotting, etc. It would probably take a lot
more than 20,000 lines of Java code to have the same functionality.
In short, the functionality of IDL allows one to quickly analyze and
visualize data or do software prototyping. We feel we can get our data
analysis done and our software prototypes up and running faster in IDL than
we could in Java. If your goal is data analysis or software prototyping, IDL
is hard to beat. If your goal is to have a nice piece of object oriented
code, you might choose Java. At the risk of stereotyping, I'd sum it up by
suggesting that if you're a data analyst you'll probably prefer IDL and if
you're a computer scientist you may prefer Java.
