Help understanding example for Inlining Matlab S-function

In https://au.mathworks.com/help/rtw/tlc/introduction-inline-s-functions.html#f34125, I am trying to follow the example under the heading "Inline MATLAB File S-Functions"
Step 5 is unclear:
"Step 5 :On the Signal Attributes tab of the Inport Block Parameters dialog box, set the Port dimensions parameter to 5."
What do I need to click on to find this? Where do I find the "Inport Block Parameters dialog box"?
Thanks,

You double click to Inport block, choose the Signal Attributes tab

I think step 5 for example about code generation from S-Function block.
So when you change contant block to inport block, generated code will same below.
/* S-Function (timestwo): '<Root>/MATLAB S-Function' */
/* Multiply input by two */
{
int_T i1;
const real_T *u0 = ×2_B.Gain[0];
real_T *y0 = ×2_Y.Out1[0];
for (i1=0; i1 < 5; i1++) {
y0[i1] = u0[i1] * 2.0;
}
}
5 dimenssion of inport is maximum of for loop
