REPEAT statement

Arguments

statement

A single or compound statement to be repeatedly executed.

Discussion

The REPEAT statement repeatedly executes a statement until a condition ­occurs to transfer control to another statement. This statement is functionally equivalent to the DO FOREVER statement.

Statement can be on the next logical line. It is executed repeatedly until control is explicitly transferred to a label outside of the scope of statement, or until an EXITLOOP is executed.
