Learning Manual 2.18 2.41 Organizing pieces with variables

[Kevin Tough]

Hi Folks,
I'm trying to get up to speed with variables but I am missing something
obvious or the documentation is not clear.

In the example the escaped \cm generates an escaped character not
recognized error message. If I stick it in a layout block it is
recognized. Then however the variable is not longer seen outside that
scope.

The use of the variable name "name" to hold the value "Wendy" causes a
warning that "name" is a keyword.

Here is my code...

\version "2.18.2"

\language "english"

\layout {
   indent = 0.0\cm
 % \omit Voice.StringNumber %defeat number display above treble staff
  width = 4\cm 
}

name = "Wendy"
aFivePaper = \paper { paperheight = 21.0 \cm }

% Now use these variables...
\paper {
  \aFivePaper
  line-width = \width
}

{
  c4^\name
}
