do loop

The do loop will execute forever:

statements

loop

Optionally the do loop can have conditional tests at the beginning or end of the loop (but not

both).

The variations for the do loop command are:

do [statements] loop

do while <condition> [statements] loop

do until <condition> [statements] loop

do [statements] loop while <condition>

do [statements] loop until <condition>

An example:

A = 0

A = A + 1

loop while A<100

The difference between putting the conditional at the beginning or end of the loop is if the

conditional test (while or until) is placed after the loop command the loop will always be

executed at least once, even if the test is false. Placing the test before the do means the loop

does not get executed if the condition is false.

A = 5

do while A<3 ; this test is false

A = A + 1 ; so this command never gets executed

loop

A = A + 1 ; this command will get executed once

loop while A<3 ; even though this test is false
