repeat loop

programming (Or "do loop") A loop construct found in many

imperative programming languages which repeatedly executes

some instructions while a condition is true.

It is found in Pascal, BASIC and C ("do" form). The

condition may be tested with a "while" or "until" keyword.

In constrast to a while loop, the "loop body" is executed

once before the condition is tested. This is useful when the

condition depends on the action of the loop body. In the

following BASIC loop "Hello" is printed once despite the fact

that the condition is false;

i = 2

repeat

print "Hello"

i = i+1

until i@#0
