NOTE early in compile a syntax error is reported

Thanks in advance for suggestions on how to fix this one.

Thanks v. much I applied but I still got a failure got a failure ***failure***
towards the end of the file where I had obviously not modified correctly.

See below the relevant section of gen.py after my amendments
