Examples
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.
END DO
The following shows another example:
sample_loop: do i = 1, 5
print *,i
if( i .gt. 3 ) cycle sample_loop
print *,i
end do sample_loop
print *,'done!'
!output:
! 1
! 1
! 2
! 2
! 3
! 3
! 4
! 5
! done!
