/sys$common/syshlp/helplib.hlb PASCAL, Declaration Section, Const Declaration *Conan The Librarian (sorry for the slow response - running on an old VAX) |
A CONST section defines symbolic constants by associating identifiers with compile-time expressions. Syntax: CONST {constant-identifier = constant-expression};... The 'constant-identifier' is the identifier of the symbolic constant being defined. The 'constant-expression' is any legal compile-time expression. The Compaq Pascal compiler must be able to evaluate all of the components of a compile-time expression when it compiles the program. Example: CONST Year = 1981; Month = 'January' Almost_Pi = 22.0/7.0; Lie = FALSE; Untruth = Lie; This CONST section defines five symbolic constants. 'Year' is declared to be the numeric value '1981'; 'Month' is declared to be the string constant 'January'; 'Almost_Pi' is declared to be the result of '22.0' divided by '7.0'; 'Lie' is declared to be the Boolean value 'FALSE'; and 'Untruth' is declared to be of type 'Lie.'
