The sample program below finds the total of numbers 1 to 10.
O9500;
#1=0;Initial value of the variable to hold the sum
#2=1;Initial value of the variable as an addend
N1 IF[#2 GT 10] GOTO 2; Branch to N2 when the addend is greater than.
10
#1=#1+#2; Calculation to find the sum
#2=#2+1; Next addend
GOTO 1; Branch to N1
N2 M30;End of program
Specify a conditional expression after WHILE. While the specified
condition is satisfied, the program from DO to END is executed. If the
specified condition is not satisfied, program execution proceeds to the
block after END.
WHILE [conditional expression] DO m ; (m=1,2,3)
END m ;

While the specified condition is satisfied, the program from DO to END
after WHILE is executed. If the specified condition is not satisfied,
program execution proceeds to the block after END. The same format as
for the IF statement applies. A number after DO and a number after END
are identification numbers for specifying the range of execution. The
numbers 1, 2, and 3 can be used. When a number other than 1, 2, and 3
is used, P/S alarm No. 126 occurs.
