Diagnosis
You created a step loop. To do this, both the position and the size ofthe loop block are defined as a rectangular section. One corner of theloop block is already fixed by the field on which the cursor stands.

Procedure
Place the cursor so that the opposite corner of the the loop block isfixed and choose Select block end.
In most cases, loop blocks are defined as one-line loop blocks. Therectangular section is thus special in that it is part of a line.
The system first generates a minimal step loop where the loop block isrepeated twice.
If you want more than two repetition blocks, place the cursor on thedesired last line of the step loop area and select Select loopend.
Then, by pressing F3=Back, you can leave step loop processing andreturn to the fullscreen.
