set or reset the index from an array with visa?

I'm controlling my FPGA-Card (7833R) on RLP with a C-programmed tool with the VISA-Interface.

 

Now im introducing the use of arrays.

 

The use of arrays still works. With each read or write command ( 

viPeek32(FpgaTarget, address+adressfromarray, &vari);

, it's iterating the index pointer from the array and is reading the next element.

But is there a command to set or reset the index pointer from the array? Is the only solution to run throw the hole array?

 

Thanks for your help!

Hi,

 

sorry but the issue you are working with is RLP or Registry Level Programming. This is not highley supported by National Instruments.

 

Maybe closing and reopening the VISA-session could be a workaround.
