CRLIB, what next?

[HP67]

I tried to create a library today on a 50g. CRLIB appears to work, the library goes on the stack. I saved it in port 0. The library shows up in port 0. I warmstart and the library shows up in the LIB menu. I also did libno ATTACH just for fun, in the HOME directory.

Alas, I cannot access any of the commands in the library. I hope I missed something minor.

Any suggestions where I messed up or what to check?

Thanks.
