Thanks for expounding my perhaps-overly-subtle rhetoric.

Are you perhaps recalling a superannuated restriction. As an
experiment, I readily created (though with NFS, not JCL nor TSO)
'&SYSUID..&SYSUID', then viewed it and deleted it with DSLIST.

the Babel of EBCDIC (need I say it?) code pages. And VM creates
problems with passwords containing '@', '#', '"', perhaps others.
