In both examples the statements following the NEXT -statement are ignored if value = 3 .

In the first example this is achieved by a conditional NEXT -statement, whereas in the second example an unconditional NEXT -statement has been integrated into an IF -loop.

WHILE value > 0 LOOP
   NEXT WHEN value = 3 ;
   tab( value ) := value REM 2 ;
   value := value / 2 ;
END LOOP ;

WHILE value > 0 LOOP
   IF value = 3 THEN NEXT ;
   END IF ;
   tab( value ) := value REM 2 ;
   value := value / 2 ;
END LOOP ;

These are two examples of chained FOR -loops which are needed to calculate the values of the elements of a two-dimensional array.

In the first example the succeeding statements for the inner loop are ignored if i = j.

In the second example the process is continued with the next passage of the external loop if i = j .

lbl_1 : FOR i IN 10 DOWNTO 2 LOOP
   lbl_2 : FOR j IN 0 TO i LOOP
      NEXT lbl_2 WHEN i = j ;
      table ( i, j ) := i + j - 7 ;
   END LOOP lbl_2 ;
END LOOP lbl_1 ;

lbl_1 : FOR i IN 10 DOWNTO 2 LOOP
   lbl_2 : FOR j IN 0 TO i LOOP
      NEXT lbl_1 WHEN i = j ;
      table ( i, j ) := i + j - 7 ;
   END LOOP lbl_2 ;
END LOOP lbl_1 ;
