Number of psvar entries

Number of psvar entries

[Mikael Magnusson]

The manpage tells us

psvar <S> <Z> (PSVAR <S>)
 An array (colon-separated list) whose first nine values can be used
in PROMPT strings.  Setting psvar also sets PSVAR, and vice versa.

but

% psvar[25]=hello; print -P %25v
hello

Am I missing something?

Evidently the manual page is...  That restriction certainly goes way
back to very early versions of zsh.  It's possible numeric argument
handling in prompts was original limited and we upgraded it to handle
any integer that fits in integer precision; I don't actually remember
that happening, but I do remember the prompt code evolving quite a lot.
If it happened, I've a suspicion it would have been way back before the
CVS archive.

In which case the manual page simply needs updating.

} Evidently the manual page is...  That restriction certainly goes way
} back to very early versions of zsh.

I happen to have sitting around a binary of zsh 2.4.306 beta, and at
that version the documentation is correct (and really strange stuff
can happen if psvar[1,9] are all empty).  By 3.0.5 indices above 9
are usable.  So there's a chance the change is in CVS somewhere if
that's interesting for some reason.

} In which case the manual page simply needs updating.

I'd say so.
