Ordinary constants declarations are no different from the TP implementation. You can only declare constants of the following types: Ordinal types, Real types, Char, and String. The following are all valid constant declarations:
Const
e = 2.7182818; { Real type constant. }
a = 2; { Integer type constant. }
c = '4'; { Character type constant. }
s = 'This is a constant string'; {String type constant.}
Assigning a value to a constant is not permitted. Thus, given the previous
declaration, the following will result in a compiler error:
s:='some other string';
