Can I nest compilation of files?

[Anaswara Nair]

I'm using BISON to create a parser for a new language more or less similar
to Ada. I wanted to nest compilation of different files and store the
variables used in each variables in a structure so that it is available for
other files too.
What should I do to make it possible?

I tried using system command, but the variables were not available to the
next file being compiled.

Thank you in advance.
