Diagnosis
You have chosen either the Select block end function, in orderto extend a block, or a box where all the screen elements are selected.
This block contains parts which belong to a loop block and some whichdo not. This kind of overlapping is not allowed.

Procedure
The block can either contain no loop elements or it must lie completelywithin the first loop block, but not in any loop repetition lines.
If you want to move or delete an entire loop area, place the cursor inthe loop area and select the Loop function.
If you want to move or delete a box containing a loop area, you mustmove the box and the loop area separately. You can process a box on itsown (i.e. without the elements it contains) by placing the cursor onany character of the box edge and choosing the Graphical elementfunction.
