[plt-scheme] Text-contents to a function variable

Hello,

using string->number would be an obvious option.

On a side note, I think it is potentially misleading to talk about
"turning [something] into a numerical variable". A program can turn
*values* of one type into values of another type, but *variables* are
no first class values in Scheme, but rather named locations holding
values. Speaking about turning anything into a variable only really
makes sense in the context of code transformations, for example when
discussing program design or when looking at code that is part of a
compiler.

Ciao,
Thomas
