No, your code has 2 syntax errors that scram is correctly reporting to you.
The syntax error messages are what come out of PCCTs, and they're not
always totally clear, but generally at least flagged on the right line.
One of the developers has been working on this aspect of error reporting,
btw, and there will be some improvements coming soon.

You mean:
Replicated(iBit) := Arg ;
I assume.

Likewise:
Combined := Combined and Arg(iBit) ;

With those changes, this code analyzes fine with my working copy.
