GDL is a free alternative to IDL, and apparently is fully syntax compatible. It can be downloaded from http://gnudatalanguage.sourceforge.net/.

I successfully installed it about a year ago on my powerbook running X.3, but had to remove it later because it messed with ImageMagick libraries.

Particularly statisticians. I have been looking for open sources that extract ascii information from fits files. Can GDL (GNU Data Languages) be a solution?</p> Not many are aware of IDL.

Anyone that plans to read in FITS files for use in C or Fortran are better off using the CFITSIO function calls directly in their programs.

IDL users can use the IDL-Astro library. The easiest of the routines to use are readfits() and mrdfits(). The IDL-Astro library also contains numerous functions to manipulate every element of a FITS file (images, table columns, headers, etc), see the IDL-Astro contents.
