The manual explanations for debug and version are not clear to me.  SAMPLES does
not show any debug statements and only 1 version statement.

Given:  dmd.exe -debug-5 -debug=RED -debug="GREEN" myprog.d

Which of the following are valid statements and should compile their code into
myprog (and why)?

1.  debug {...}
2.  debug (4) {...}
3.  debug (5) {...}
4.  debug (6) {...}
5.  debug ("4") {...}
6.  debug ("5") {...}
7.  debug ("6") {...}
8.  debug (RED) {...}
9.  debug ("RED") {...}
10. debug (GREEN) {...}
11. debug ("GREEN") {...}
12. debug (RED && GREEN) {...}

Many of the explanations in the specification are vague.  It's part of 
being a pre-1.0 language.

I think you need to leave out the quote marks (").  I haven't done any 
of these specific experiments, but I think debug/version names follow 
identifier rules, i.e. ...
OK: 	RED, GREEN, GREEN_COLOR, Green_Color, Whatever


Numbers are also supposed to be allowed as identifier, but I've never 
tried that.

I have very little with debug, but I've use version a lot more often.

Here's some examples that I've worked up...

Got my compiler working now.  As you indicated, 5,6,7,9,11, and 12 won't
compile.  When executed, 1, 8, and 10 appear to have compiled in, (the command
line appears to have accepted both -debug=RED and -debug="GREEN").  Correcting
my command line to use -debug=5 instead of -debug-5 adds in statements 2 and 3.
Apparently any form of -debug... seems to compile statement 1.  Multiple -debug
options are all accepted and used correctly, with multiple numerics accepted as
either 5 or "5" format and only the last one used by the compiler.  I presume
this is as it should be.  Thanks.
