scheme compile error

[Gianmaria Lari]

This program does not compile because myvar is not defined.

\version "2.19.82"

test = #(cond

         ((= myvar 0) "zero")

         ((= myvar 1) "one")

          )

\markup \test

And this is the fixed version

\version "2.19.82"

myvar = 1

test = #(cond

         ((= myvar 0) "zero")

         ((= myvar 1) "one")

          )

\markup \test

The errors I get when I compile the wrong code are the following

C:/Users/GIANMA~1/AppData/Local/Temp/frescobaldi-gtv7n2o_/tmpj0pm3z6i/document.ly:2:9: error: GUILE signaled an error for the _expression_ beginning here

test = #

(cond

C:/Users/GIANMA~1/AppData/Local/Temp/frescobaldi-gtv7n2o_/tmpj0pm3z6i/document.ly:7:9: error: not a markup

\markup

\test

For me these are not enough clear to understand the problem. Is there any way to get a more precise indication of the error I did?

Thank you, g.
