Pascal, as defined by Wirth, is a general-purpose programming language with the following '''reserved words''': array, begin, case, const, do, downto, else, end, file, for, function, goto, if, label, nil, of, packed, procedure, program, record, repeat, set, then, to, type, until, var, while, with.  The following reserved words are '''operators''': and, or, not, div, mod, in.  Built in simple '''data types''': integer, char, boolean, real.  In addition, arrays of data types, files of data types, and records (structures) can be defined, as well as enumerations (called scalars).  Unique among major programming languages is the support of '''sets'''.  Built-in '''functions''': abs, arctan, chr, cos, eof, eoln, exp, ln, odd, ord, pred, round, sin, sqr, sqrt, succ, trunc.  '''Operators''': + - * ( ) < > = <> >= <=
