Question about \paper{} as a curiosity

[Joshua Nichols]

I noticed something I was typesetting recently:

Whenever I mark my margins inside \paper{} before setting the #(set-paper-size "x"), it ignores any indent, top-margin, or bottom-margin commands. But, whenever I set the paper size before the margins, it obeys the other commands.

How come? I glanced over the reference, and couldn't find anything about it.

Snippet below:

\paper {

  #(set-paper-size "letter")

  right-margin = 1\in

  left-margin = 1\in

  top-margin = 1\in

  bottom-margin = 1\in

  indent = 0\in 

  }

= correct output

\paper {

  right-margin = 1\in

  left-margin = 1\in

  top-margin = 1\in

  bottom-margin = 1\in

  indent = 0\in

  #(set-paper-size "letter") 

  }

= incorrect output

Sincerely,

Josh
