numbers in variable names

[Kieren Richard MacMillan]

Hello, all --

I use a lot of variables, especially when breaking larger works  
across multiple pieces (and thus .ly files).

I'd like to name my variables numerically, e.g.,

    file01.ly
        global01 = { ... }
        notes01 = { ... }

    file02.ly
        global02 = { ... }
        notes02 = { ... }

    score.ly
        \score { << \global01 \notes01 >> }
        \markup { "splitter text" }
        \score { << \global02 \notes02 >>  }

but Lilypond (more likely LaTeX) won't let me. Does anyone know a  
workaround?

Thanks,
Kieren.
