i want to save some DBs in the load memory (mark as UNLINKED) and to transfer one of them to the work memory depends on the machine pallet type. i tried to do it with SFC20 (BLKMOV) but all the time i get an error - 8092 on the RET_VAL. if i do the same but without UNLINKED marked it works just fine (but then it takes plase in the work memory).

ANYBODY KNOWS WHAT MY PROBLEM IS?
 
Hi Ziv,

you have to use the SFC 83 "READ_DBL" to copy a datablock from the load moemory to the work memory. See the Step 7 docs for more information.
