Lo, in the beginning there was darkness, and David Stern said, "Let
there be AE." And David knew PL/1 and APL and FORTRAN, and he looked
upon AE and saw that it was good. And there was morning and there was
evening on the first day.
On the second day, David Stern said, "Let there be SOL." And lo, it
too, was terribly cool.
On the third day, David Stern said, "Let there be IDL." As to
whether it is gnarly, there is a Usenet group to decide thereof.
****
AE was used originally to analyze data from an Atmospheric Explorer
satellite, and SOL, to analyze data from Orbiting Solar Observatory 8
(c. 1975). David Stern developed both while working for the Laboratory
for Atmospheres and Space Physics at the University of Colorado. He then
got the enterpreneurial itch, and formed RSI. The first version of IDL I
saw (for RSX-11 on PDP-11's) was in late 1979. It had a lot in common
with SOL.
If anyone knows the prehistory of AE, we can probably regard it as
apocryphal and write reams of commentary on it.
