Astrobe Forum

The Programming in Oberon Tutorial by Niklaus Wirth has been replaced by a later revision which is more compatible with the latest version of Oberon which is used in Astrobe. We have now added a bookmarked table of contents and uploaded it to the Oberon page on the Astrobe website.

The following is a list of known outstanding differences:

• Data type LONGINT is eliminated.
• COPY is no longer needed:
  

  Code: Select all

  COPY(S.s, a);

  becomes

  Code: Select all

  a := S.s;

• Only global objects and strictly local objects may be accessed in a nested procedure. Objects declared in its outer level procedure(s) are not visible in a nested procedure.
