Also below are several references to other sites of interest to standard Pascal in one form or another.
The ISO 7185 Pascal standards is unique in that they did not seek to remake the existing Pascal language as defined by Niklaus Wirth. Instead, they simply defined Wirth's Pascal in a more formal form, and eliminated the abiguities of the original language.
The first ISO standard essentially is the original language. Pascal has been subsetted, modified and worse. But in it's original form, Pascal may be the most carefully constructed, documented and standardized language in existence.
Pascal is, unfortunately, very much a "great improvement on it's successors", and continues to be usefull for all programming work.
