Introducing the new 7th programming language
The 7th® programming language is based on the concepts of Charles Henry Moore's "Problem Oriented Language".
Because of its unique interpreting compiler, Forth™ makes programming quite easy and a compiled program – called “word” – is very compact.
The programming language 7th runs as such an interpreting compiler for stability and portability on the JVM.
Beside Forth's major features 7th brings several enhancements, to name some
• object orientation
• help function
• redirecting of program output
• complex numbers
• array and array functions
• pattern matching
The functions of the "Klassenbibliothek" formerly found here are all included in 7th.
7th comes with an complete development system, with an editor and a code beautifier that does syntax highlighting and correct indentation in a very small package.
To comment out the rest of the line use //
// Loop through numbers from 1 to 10.000
to show the stack behavior of a word use ( -- ) "-" two times!
: facul ( n -- facul )
to comment out a part of a line use (* *)
row i @ (* occupied *) 'x' == if
Text inside round braces is interpreted as an algebraic expression ( )
***Don't waste too much time, if the IDE won't start over the web. Go to the last tab Download and click …the 7th IDE. If You find 7th useful, You will use it locally anyway.***
Webstart on Linux
To execute an .jnlp file on a Linux System You have to install IcedTea Webstart first:
sudo apt-get install icedtea-netx
After starting the IcedTea Webstart program You have to answer the Security Warning dialog. The later stays sometimes hidden behind the IcedTea Webstart main window.
To start the tryout.jnlp file type javaws tryout.jnlp in the command window or choose IcedTea Java Web Start from the tryout.jnlp file context menu on the graphical desktop.
