Thanks, Thomas.  It sounds like ruby is already "strict" in the perl 
sense.  As for warnings, I'll enable them on the goocher, which is what 
I call a dos command that I comment out at the end of a script:  Thus

# perl client2.pl >text59.txt 2>text56.txt
  __END__
becomes, in ruby, with warnings enabled:

# ruby -w client2.rb >text59.txt 2>text56.txt
  __END__

Cheers.
