>From the comments:
"The variables yyinput and yyoutput are the text files which are used
by the lexical analyzer. By default, they are assigned to standard
input and output, but you may change these assignments to fit your
target application (use the Turbo Pascal standard routines assign,
reset, and rewrite for this purpose)."

Thankfully, we also have:

Which can turn any TStream descendant into a TextFile. Just change Assign as
in the comment above into AssignStream, everything else is totally the same.
