Hello,

For searching pattern, I suggest checking the following clustered threads:

HD_Searching Patterns in DBs-Compare DBs

And also the following topics on indirect addressing:

1. Information on the topic of "Indirect addressing"
   
   
2. STEP 7 -- Creating S7 programs -- Indirect Addressing

for a more specific case, explain your requirement in details for members here for more comments.

I hope this helps,
