Marc - Thanks for the tip. Looks like the bug slipped back in!
My system generates:
{ $ I Unit1.Lrs}
I checked my Codetools options/Space.
In space before I only had number checked. When I unchecked it, I got:
{$ I Unit1.Lrs}
which was better, but not correct.
In space after, when I unchecked number, I got:
{$I Unit1.Lrs}
Bug indentified!!
