This is driving me crazy.
Why does this snippet give a compile error in the function declaration?
error: syntax error before `('
program PrtTst2;
uses
  GPCStringsAll;
// from the gpc.pdf manual this is the way a function should look
//
// function function_identifier (parameter list): result type ;
// declaration part
// begin
// statement part
// end;
function fixDateYear(thisDate : String(255)) : String(255);
  begin
  end;
begin {main}
end.
For function parameters and and return type Pascal allows only
type _name_.  Change your program to:

program PrtTst2;

type String255 = String(255);

function fixDateYear(thisDate : String255) : String255;
        begin
          fixDateYear := thisDate
        end;

begin {main}
end.

and gpc will accept it.
