This is what the (new) Stanford Pascal compiler does:

program TESTLSTR ( OUTPUT ) ;

var ZEILE : array [ 1 .. 200 ] of CHAR ;
     I : INTEGER ;

begin (* HAUPTPROGRAMM *)
   ZEILE := 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
            'bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb'
            'cccccccccccccccccccccccccccccccccccc'
            'dddddddddddddddddddddddddddddddddddd'
            'eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee' ;
   WRITELN ( ZEILE ) ;
   MEMSET ( ADDR ( ZEILE ) , 'b' , 200 ) ;
   WRITELN ( ZEILE ) ;
   for I := 1 to 200 do
     ZEILE [ I ] := '=' ;
   WRITELN ( ZEILE ) ;
end (* HAUPTPROGRAMM *) .

that is: long strings may be concatenated simply by closing
the string constant on one line and reopening it on the next line.
