I wrote a Genuine PASCAL to C "converter" (compiler!) as part of a compiler
used to automatically generate communication protocols from an extended state
machine description.  My conclusions at the end of my task was that it was
"easy" but....  The major problems if I remember correctly were in dealing with
nested routines (i.e. one routine defined inside another) and the scope of
variables with in these types of structures.  I ended up renaming things in a
uniquie systematic way and then declaring (for variables) them to be external.
Other problems arose in trying to deal with the different formats of I/O
statments.  Generally one Pascal write statment converted into one or more C
printf's.  There were other problems but mostly it was just straight text
translation.  My preference would be to use a text editor to do the job.
