This summer, 40 years ago “The Pascal Programming Language (Revised Edition)” was published

Posted by jpluimers on 2013/07/01

Niklaus Wirth developed the Pascal Programming Language in the early 1970s.

This summer, 40 years ago, he published an important report in that era: “The Programming Language Pascal (Revised Report) July 1973“.

The report describes the language after it had been use in a while and includes a few language changes (packed records and arrays, file handling behaviour, and a few others) introducing a period of language stability.

If you are part of the Swiss research community, you can download the original PDF at

If you are not, then Switch.ch will block access.

However, there are at least 2 ways to view the report:

An earlier (November 1972) draft of the report is also available.

If you by accident press Ctrl-Z on the Linux console, use fg to un-suspend that task

Posted by jpluimers on 2013/07/01

The Linux console has different shortcut keys than many people are used to, so Ctrl-Z is not “undo”, but “suspend”. It sends and returns you to the command prompt.

The easiest way to undo that is to type fg, which brings back the suspended process into the foreground.

A nice post with a bit more background information is Bg, Fg, &, Ctrl-Z – 5 Examples to Manage Unix Background Jobs.
