You probably want something like this:

  .de END
  ..
  .
  .de something
  .  de something-aux END
  ps: exec \\$*
  .  END
  \Y[something-aux]
  ..
  .
  .something 50 (hello) 100

which gives

  x X ps: exec 50 (hello) 100
  +

in the intermediate output.

It does -- in the example above you use `,' instead of `.' ...

  .nr x 5i
  .de y
    ps: exec
    \nx u 0 rlineto stroke
  ..

gives me these lines in the intermediate output:

  x X   ps: exec
  +  360000 u 0 rlineto stroke
  +

Number registers are always treated without scaling if you omit a
scaling indicator.  Where's the problem?  You explicitly specify
`5i'...

Please explain.  It's not clear to me what you want to achieve.
