This procedure processes Pascal declarations: Constants, Types, Variables, Procedures, Functions, and if declarations are not in the Interface part of the unit, also Lables, Constructors and Destructors are processed. Before declarations are processes, statement compiler switches are reset to module compiler switches. This procedure is called from program compilation, unit interface and implementation compilation and …

Turbo Pascal constants can be of two types: ordinary constants which are only stored to the symbol table and typed constants which are also embedded into the program. Therefore, typed constant values are stored into a separate symbol table.

This procedure processes and stores the value of typed constants. For complex types like Arrays, Records and Objects recursion is used to process elements and fields.

This function checks and processes string constants. It processes characters enclosed with single quotes, control characters and characters defined with the ASCII code (#code).
