The page is dedicated to holywars about Pascal language (any kind of pascal included).

If you're Pascal developer being involved into a next flame about Pascal language, you're encouraged to use the page. Pascal has something of a stigma as an "educational, and therefore weak" language, but it has nothing in common with a real life.

Why do we use Pascal

(if you don't use (Object) Pascal, please don't edit the section)

Often programmers are free to choose their tools, especially then coding as a hobby (rather than for their living). Lots of Pascal programmers choose the language because of:

Q&A

Q: Why there're so many limitations on what expressions i can use in "for" and "while" operators? Why can't i define a really complex type in one line?

A: to force you to create maintainable and readable code


Q: Pascal doesn't allow to specify complex types without intermediate types. I.e. "an array of pointers to a function that accepts 2 ints and returns a pointer to function that returns a float" <c> float (*(*a[10])(int, int))() </c>

A: Has it any advantage to define no intermediate type? <delphi> type

 TFloatRetFunc = function : single; 
 TSomeArray = array [0..9] of function (a, b: Integer): TFloatRetFunc;

</delphi>

Advantages over C/C++

  • no preprocessor (better code reading and understanding)
  • no hardly readable and poorly debugged STL
