Multiple Loop Limits
- Lower limit is the maximum of several expressions
- Upper limit is the minimum of several expressions
for i = 1 to 8
for j = max(i-3,1), min(i,5)
A[i+1,,j+1] = A[i,,j] + B[i,,j]

Exit in The Middle of a Loop
Some statements may execute more number of times than others
1.
2.
3.
4.
5.

j = 0
loop
j = j + 1
A[j] =···
if j > 10 then exit
= A[j+1]
endloop |
line number 4 executes eleven times, therefore,
