SORT, UNIQ and FILE_TEST
HOMEPAGE:

For those who haven't heard of GDL before:
FEATURES:

Pointers, Objects, Structs,
Arrays, System variables,

All operators, All data types,
_EXRA and _REF_EXTRA keywords...
The file input output system is fully implemented
(Exception: For formatted I/O the C() sub-codes are not supported yet)
Most image file formats (jpeg, tiff, ...) are supported.
netCDF files are fully supported.

Overall more than 210 library routines are implemented (among them the
EXECUTE function). For a list enter HELP,/LIB at the command prompt.
Graphical output is partially implemented. The PLOT and TV commands
(along with WINDOW, WDELETE, SET_PLOT, WSET, TVLCT) works (important
keywords, some !P system variable tags and multi-plots are supported)

A GUI (widgets) is not implemeted yet.
