Some of C-Shell's metacharacters, namely those concerned with histroy, can be
changed through the use of the "histchars" environment variable.
 
Is there any reason why the pipe metachar can't me treated in a similar way
under AmigaDos?  Then you could use any pipe character you wanted.

(minor irrelevant nitpick, not all Cshells allow this. Sigh)

A good idea, though make it a shell-local variable rather than an environment
variable so you can set it in a script without screwing up everything else on
the system. Remember, Amiga environment variables are system-global.

I think it would be still better to have BOTH, so that you can let the user
set his favourite once and forget it, and still allow scripts their own
special preference if they need it.

I disagree:

Put it in his shell RC file, and then all his interactive shells will have
it. That's effectively "global", without breaking scripts:

No, batch scripts need to have a standard environment, particularly for things
like metacharacters.

If you have a global PIPECHAR variable, it needs to be ignored when not in
interactive mode. (This is the MOST hosed feature of the C shell on UNIX, that
scripts have to deal with whatever wacko stuff a user puts in their .cshrc)
