- This is no advantage.
-
- A program is a model: an abstraction expressed in a representation. The
- Pascal seperation of constant, type, and variable classifies the tools of
- representation; it is irrelevant within a program. Would you require a
- cook to measure out all the ingredients specified by tablespoons before
- measuring any ingredient specified by cups?

-
- True to a point. See Kernighan's _Why Pascal is not my Favorite Programming
- Language_ for the limitations of nested procedures.

-
- Besides which, people who learn Pascal first seem to take three or four
- times as long to learn how to use C pointers as people who don't learn
- Pascal at all, and Pascal introduces people to some really poor habits.
-
- The classical Pascal expression of a loop-and-a-half cannot be written
- as a while() because Pascal's expression syntax is too weak. It cannot
- be written as a loop-and-a-half because Pascal doesn't allow a `break'
- from a loop. What results is a circumlocution involving more code in
- control flow and temporary variable managing than in solving the problem;
- worse, one branch of an if-then is related to the circumlocution and
- one to the problem to be solved. This is a very bad form of incohesion:
-
- if not X
- manage the loop
- else
- solve the problem
-
- This seems to me as damaging to potential software designers as BASIC
- is claimed to be to potential programmers.
