BLISS

BLISS merupakan bahasa pengaturcaraan sistem yang dimajukan di Universiti Carnegie Mellon oleh W. A. Wulf, D. B. Russell, dan A. N. Habermann sekitar 1970. Ia kemungkinannya bahasa pengaturcaraan sistem paling terkenal sehingga C muncul beberapa tahun kemudiannya. Semenjak itu, C berkembang dan BLISS lesap begitu sahaja. (Semasa C baru bermula, beberapa projek dalaman Bell Labs sedang berdebat mengenai kekuatan BLISS vs. C.)

Contoh kod sumber

Contoh berikut diambil dari buku Panduan Mengaturcara Bliss (Bliss Programming Manual):

MODULE E1 (MAIN = CTRL) =
BEGIN
FORWARD ROUTINE

CTRL,

STEP;

ROUTINE CTRL =
!+
! This routine inputs a value, operates on it, and
! then outputs the result.
!-

BEGIN

EXTERNAL ROUTINE

GETNUM, ! Input a number from terminal

PUTNUM; ! Output a number to terminal

LOCAL

X, ! Storage for input value

Y; ! Storage for output value

GETNUM(X);

Y = STEP(.X);

PUTNUM(.Y)

END;

ROUTINE STEP(A) =
!+
! This routine adds 1 to the given value.
!-

(.A+1);

END
