Description

Procedure identifiers are identifiers that have been associated with a procedure using a procedure declaration.

Example

Here is an example of a procedure declaration.

   (*******************************************************************
   ** PURPOSE: Writes the contents of one file into another.
   ** ARGUMENTS:
   **    'f' - the input file
   **    'g' - the output file
   ** NOTES: It is up to the caller to open and close the files.
   *)
   procedure WriteFile(var f, g : text);
   var
      c : char;
   begin
      while not eof(f) do
         begin
            read(f, c);
            write(g, c)
         end
   end;

Syntax

(NOTE: for clarity some parts of the syntax are omitted, see Irie Pascal Grammar for the full syntax):
