GDL (GNU Data Language) is a freeIDL (Interactive Data Language) compatible incremental compiler that has full syntax compatibility with IDL 6.0. It supports all IDL language elements including pointers, objects, structs, arrays, system variables, common blocks, assoc variables, all operators and datatypes, and _EXTRA and _REF_EXTRA keywords. The file input output system is fully implemented (with the exception of C() sub-codes for formatted I/O); overall, more than 120 library routines are implemented. NetCDF files are fully supported; graphical implementation is partially implemented.
