Seed7 is a general purpose programming language designed by Thomas Mertes. Seed7 project is a higher level language compared to Ada, C/C++ and Java.

The Seed7 interpreter and the example programs are open-source software. An open-source Seed7 compiler is also under development.

In Seed7 new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used where it brings advantages and not in places where other solutions are more obvious.

Although Seed7 contains several concepts of other programming languages it is generally not considered as a direct descendant of any other programming language.

Here are some key features of "Seed7":
User defined statements and operators.
Types are first class objects (Templates and generics can be defined easily without special syntax).
Predefined constructs like arrays or for-loops are declared in the language itself.
Object orientation
Strong typing
exception handling
overloading of procedures/functions/operators/statements
Various predefined types like resizable arrays, hashes, bitsets, structs, color, time, duration, etc.
Runs under linux and various unix versions. A windows version is under developent
The interpreter and the example programs use the GPL license, while the runtime library uses the LGPL license.

What's New in This Release:
- The functions bigLength, seek, bigTell were added to
support files with 64 bit offsets.
- The file functions getwd, getln, read and readln were
changed to remove 'r' before 'n'.
- Parameters of type bigInteger were changed to use call by
reference.
- The functions ord and conv for the bigInteger type were
added.
- The putf function (to copy a string to a file) was changed
and a writef function was added.
- Functions to split and join strings and a check for that
functions were added.
- Comparisons = and for arrays were added.
- An implementation for 'set of string' based on the 'hash'
type was added.
- Keyboard functionality was moved into the new file
kbd_rtl.c.
- A new makefile makefile.msy for MinGW MSYS compilation was
added.
