Statement: Interrupts the current execution cycle of the innermost (or named) DO construct.
(Optional) Is the name of the DO construct.
When a CYCLE statement is executed, the following occurs:
The current execution cycle of the named (or innermost) DO construct is terminated.
If a DO construct name is specified, the CYCLE statement must be within the range of that construct.
The iteration count (if any) is decremented by 1.
The DO variable (if any) is incremented by the value of the increment parameter (if any).
A new iteration cycle of the DO construct begins.
Any executable statements following the CYCLE statement (including a labeled terminal statement) are not executed.
A CYCLE statement can be labeled, but it cannot be used to terminate a DO construct.
Execution of a CYCLE statement that belongs to a DO CONCURRENT construct completes execution of that iteration of the construct.
The following example shows a CYCLE statement:
DO I =1, 10
A(I) = C + D(I)
IF (D(I) < 0) CYCLE ! If true, the next statement is omitted
A(I) = 0 ! from the loop and the loop is tested again.
The following shows another example:
sample_loop: do i = 1, 5
if( i .gt. 3 ) cycle sample_loop
end do sample_loop
