in thread windows environment variable regression
Yes, in *NIX land. However, I should be able to write to the registry and have subsequent shells pick up my changes. And it ALMOST works. If I write directly to the PATH, no issues. If I write the PERL_PATH variable and stick it into the PATH, then subsequent shells do NOT expand PERL_PATH in PATH. If, however, all I do is fire up the Environment Variable dialog, see that all my changes are there and then click OK (no editing, no updates), the NEXT command box has the expansion properly done. That leads me to believe that there's some other 'bit' that has to be flipped. I'll have to test by looking at the registry directly which I cannot do on the current box. More to follow. |

I'll take your word for that as I know next to nothing about *nix.
On the other hand I've used and programmed every version of NT since 3.51 except 7 and rt.
If, however, all I do is fire up the Environment Variable dialog ...
That dialog is a part of the windows graphical shell. The alternative shell to cmd.exe.
After you've used that dialog and the %perl_path% has been expanded, check the path variable in the registry. It will no longer contain %perl_path%; it will have been replaced by the expansion.
So why not just put the directories into the path variable to start with?

Because I expect to change the Perl version on a regular basis and I don't want to have to parse PATH to do it.

Then don't. Just install each new version into the same place -- say X:\perl or wherever -- and then you have no need to change or edit or parse the path.
Or, if that is too simple, install new builds into versioned directories and then use:
subst p: X:\path\to\latest\version\of\perl\bin
And have p:\ in your path.
There are many ways to achieve what you want; stop trying to use the one that won't.
