Do not use hard coded L addresses. Create an array of timestamps and use a named variable in the L area. Two positive edge detections also not required.

e.g.

I have attached a program that does exactly what you want byte by byte. Try it out. If you want to reverse the order, I think the source is included. If not, I can help you with it but you will get the idea.

...and does not handle moves that overlap within the same DB as required by the OP.

This is how I did it.
Import the source and try.
Example:

Code:

      A     M      0.0
      FP    M      0.1
      =     M      0.2

      CALL  "DATA_SHIFT"
       IN_TRIGGER:=M0.2
       IN_SRCBLK :=DB402
       IN_SRCDST :=DB402
       IN_QDTM   :=10
       Done      :=#DONE
       _Ret_Val  :=#_RET

Best Regards.
