clear tcp.mute
        clear tcp.*

        reset tcp.mute
        reset tcp.*

        set tcp.mute [0 0 10 10]
        set myvar w<100 [0 0 10 10] [20 20 10 10]
        set myvar w<100 [0 0 10 10] w<200 [20 20 10 10] [40 40 10 10]

1. Specifying the scalar name/value directly -- in this case, all values in the coordinate_list get this value. For example:

      set foo 1.0
        and
      set foo [1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0]
   ...or
      set foo h
        and
      set foo [h h h h h h h h]
    

   are equivalent.
2. You can specify a scalar as a sparse coordinate_list by using the following syntax:

      scalar@x or scalar@0
      scalar@y or scalar@1
      scalar@w or scalar@2
      scalar@h or scalar@3
      scalar@ls or scalar@4
      scalar@ts or scalar@5
      scalar@rs or scalar@6
      scalar@bs or scalar@7
   

   For example, the following are equivalent:

      set foo 1.0@w
        and
      set foo [0 0 1.0 0]
   ...or
      set foo recarm@w
        and
      set foo [0 0 recarm 0]
   

3. As a shorthand for making a sparse coordinate_list from one value of a coordinate_list, "coordlist{x}@x" can be abbreviated as "coordlist@x".

Comparisons:
        val1<val2     --   if val1 is less than val2, use first expression, otherwise second
        val1>val2     --   if val1 is greater than val2 ...
        val1==val2    --   if val1 equals val2 ...
        val1!=val2    --   if val1 does not equal val2 ...
        ?val1         --   if val1 is nonzero ...
        !val1         --   if val1 is zero ...
        val1&val2     --   bitwise AND (if any bit is set in both val1 and val2)

Combinators:
        +             --   sum first expression and second expression
        *             --   multiply first expression and second expression
        +:val1:val2   --   val1*(first expression) + val2*(second expression)
        *:val1:val2   --   ((first expression)+[val1 val1...])*((second expression)+[val2 val2...])
 

  set var w<100 [0]
  set var w<100 [0] .
  set var w<100 [0] var
            

        w                 -- width of parent, pixels
        h                 -- height of parent, pixels
        reaper_version    -- REAPER version (i.e. 4.25)(requires v4.15+)

Track specific:
        folderstate       -- folder state of track, if applicable (0 for normal, 1 for folder, -n for last track in folder(s))
        folderdepth       -- positive if in a folder (how many folders deep)
        maxfolderdepth    -- highest folder depth of any track
        mcp_maxfolderdepth -- highest folder depth of any track in mixer(requires v4.15+)
        recarm            -- nonzero if track record armed
        tcp_iconsize      -- size of track panel icon column, if any
        mcp_iconsize      -- size of mixer icon row, if any
        mcp_wantextmix    -- flags indicating which extended mixer settings are desired (&1 for inserts, &2 for sends, &4 for fx parms)
        tracknch          -- number of track channels (2-64)
        trackpanmode      -- pan mode of track (0=classic 3.x, 3=new balance, 5=stereo pan, 6=dualpan)
        tcp_fxparms       -- count of TCP FX parameters visible (0-n)

Transport specific:
        trans_flags       -- trans_flags&1 is nonzero if transport centered
                             trans_flags&2 is nonzero if user wants playspeed controls visible
                             trans_flags&4 is nonzero if user wants current time signature visible
        trans_docked      -- nonzero if docked transport
        trans_center      -- nonzero if transport centered

Envelope specific:
        envcp_type        -- 4 if FX envelope (can display additional controls)
