Generating symbols from strings

[Jay Vara]

In the following program, I set xyz to the variable abc using scheme 
string->symbol as well as the usual \abc.

Instead of giving the same value for xyz, the first one sets it to string 
"abc" and the second sets it to value of abc.

What do I need to modify in the assignment of string->symbol to get it to 
be equivalent to xyz = \abc 

\version "2.18.2"

abc = IamJustAText

xyz = #(string->symbol "abc")

#(format #t "1) abc ~a   xyz ~a ~%" abc xyz)

xyz = \abc

#(format #t "2) abc ~a   xyz ~a ~%" abc xyz)
