The first project in this site is Oberon-07M compiler. Oberon-07 is programming language, defined by Niklaus Wirth in 2007, is a revision of the original version of Oberon. Current compiler extends Oberon-07 language by allowing one dimensional dynamic arrays. This compiler initially was implemented in Component Pascal. After that source codes in Component Pascal were modified for compiling by Oberon-07M compiler. Now compiler compiles itself.
