help in verilog structure

hi;
i have a tiny problem in writing a program , i want to define 8 , 8bit register and value them in a one line in a loop( for(i=1;i<8;i=i+1) Ri={Ri-1[6:0],Ri-1[7]}; ) how could i define them ?
putting number of register i "[]","{}","()", will be considered as error.

thanks in advance mona

hi,
I dont use Verilog, but does it have an ARRAY function.???
If yes, define an 8 byte array and Index them.

Thank you for reply , i found the answer . we should define it as a memory like this : [3:0] mem [127:0]. that means 128,4 bit register. i before only knew how to define a register e.g "[7:0] R " and if i wanted to use a bit of them , would call as R[4] for example ,now i have another problem ,how to call e.g third bit of 7th memory register?
