The PATH is used by the shell to find commands.
It has no effect on where groff finds that file.


I asked you to  locate  /tmac/mm.tmac to see the version number in the path
name.  Likewise for   groff --version .


I'm using  groff 1.18.1  but your input still produces the output you describe.

In my old Bell Labs Memorandum Macros documentation from 1980,
section 5.3.3.1 describes the line spacing number register  Ls .
 Ls  is also described in the  groff_mm(7) man page, under
       Number variables used in mm:


Someone else on the groff mailing list (I've lost who) suggested adding

        .nr Ls 0

before the first  .AL A  macro. 

With that in your test file, I get


                         ROYGBIV and Valve Metals

             ROYGBIV
               a.  Colors of the rainbow.
               b.  Frequency/Wavelength
               c.  The Angstrom
             Observing ROYGBIV
               a.  Refraction

                     2.  The Rainbow
                     3.  Double Rainbow
               b.  Interference/Diffraction
                     1.  Reflection
                     2.  Constructive Interference

             Valve Metals

                   aluminum

               c.  Oxide is electrochemically grown.
                     1.  Like Rust, but:
                     2.  Transparent, like glass
                     3.  An Electrical insulator
                     4.  Uses beside rectification
                           -- Insulator, store charge, capacitor
                           -- Thickness, trimmable resistor

        etc.
