Here's an article from last week:
> From: sterner@warper.jhuapl.edu (Ray Sterner)
> Newsgroups: comp.lang.idl-pvwave
> Subject: ftp site with IDL routines
> Date: 26 Jun 91 23:51:08 GMT
> Organization: Johns Hopkins University
> An anonymous ftp site is now available containing about
> 300 IDL routines which may be of general interest.
> These routines have not been tested for PV-WAVE.
>
> The routines are available as compressed tar files for unix,
> and compressed backup files for VMS (a decompress utility for
> VMS is also available from this site).

> The routines mostly fall into the following broad categories:
> Text Files, Text strings, Date & time routines, Information,
> Plotting/Graphics, Imaging, Array processing, Math routines,
> Programming routine, Miscellanious, FITS image routines.
> Many of the routines should work on any computer system, some
> require X windows, some require Postscript printers. Many have
> been run on VAX VMS, SUNOS, HP-UX, and MSDOS.
