Thanks for the prompt answer.

I added the require statements and tried with and without the gems  
requirement but it still did not give me the expected out put for   
42.<Tab>, using Tab as a word or as the key stroke.  I put a puts  
statement in the .irbc file to show that Irb reads that file.

I get the ?> prompt asking for some other input.

Any other ideas?

The q worked just fine.

Thanks.


Pete
