Why index cannot fall outside?

Thank you dude. It's a new error if "i,j" are integers.:"Error (10249): Verilog HDL Declaration error at MyDAQCard.v(107): objects with integer type cannot be declared with a range".

How to clear that? I tried my "for" loops at vc++environment, j>=0 is right,and line "@@@"is no need to write at vc++ . ；）

i need that dataout_memo[0]( j=0) as the unit data on nixie tube.

Can u help me to handle this ?

for(j=7;j>=0;j=j-1) // $$$$$

for(i=1,flag=0;i<=9;i=i+1)

if(data_reg>=CST[j])

begin

data_reg = data_reg - CST[j];

dataout_memo[j] = i;

flag = 1;

end

else if(!flag)dataout_memo[j]=0;

dataout_memo[0] = data_reg; // @@@@

data_reg = 1'b0;

Thank you!
