Thanks for detailed response and explanation.
Looks like I resolved that issue. Now I have last couple rungs of my routine where i want to add all values of my Array[52]. Any idea how to write the short formula for the CMP (Compute) instruction which will give me the SUMM (total decimal value) of all DINs in my Array[52]? I tried these options {Array[value]}; Array{value} and others but all returned with error. I dont want to write formula with summary of 52 values : Array(0)+Array(1)+........Array(52). I checked all manuals and instruction descripton so far found nothing. Do I missing something there? Thanks.
