Control

Conditionals

CPUs maintain a set of single-bit conditional code registers.

If Statements

if (<test expression>)
    <then-statement>
else
    <else-statement>

Loops

Do-While Loops

do
    <body-statement>
    while (<test expression>)

Execute the <body-statement>, evaluate the <test expression>, and continue the loop if the evaluation result is non-zero.

While Loops

while (<test expression>)
    <body-statement>

For Loops

for (<initial expression>; <test expression>; <update expression>)
    <body-statement>
