Shattered Control Flow
ZPL
logically executes one instruction at a time
•There
is a natural generalization in which statements are controlled by arrays rather than scalars
if A < 0 then A := -A; -- define absolute
•Convenient
for iterations
Let
N and Nfact be defined [1..n]
Nfact := 1;
for i := 2 to N do
Nfact := Nfact * i; -- Compute
N!
end;
