Using a counter value in a hardware pointer?

Hi,

I have a project with 200 drives where I would like to read and write data to each drive.

My idea was to use a counter value implemented in the IO address pointers but I can't seem to figure out the syntax.

The data of the first one is P#I1000.0 BYTE 19, I would place the next one on P#I1100.0 BYTE 19 and so on.

I would use the counter value to change the pointer to get the data on the corresponding drive.

I'm using the same counter to put the data in the array's I've created, for this I can use the [ ] to implement the counter value.

Kind regards
