 How the hell does DCL have 30,000+ lines of code ? :-)
(Even allowing for the fact most of it is in Macro-32)
 Also, regarding those BLISS/Macro-32 figures across the various modules
in general, I wonder how much smaller the code would have been if it had
been written in C ?

I'm not sure how Clair counted.
I just looked at the largest MAR file in DCL.  It has 10,000 lines but many are comments and many are macro definitions.  Not actual VAX instructions.
And if you look at the listing line numbers (in both MAR and C) listings, the listing line numbers reflect all the macro expansions (in Macro) or include files (in C).
