What is the purpose of + operator on strings? Can't we use setenv "${a}${b}" ?
Yes, that does the same thing, although it is a bit clumsy.
setenv a *10 setenv b *100 setenv c "${a}${b}"
instead of
setexpr c *10 + *100
Hi Simon,
I don't know. It provides the same functionality that exists, but only adds code. Is someone really going to use this?
I don't know. Perhaps we can wait and see if anyone cares?

PS: What I think would be more useful is to add substringing functionality into hush, so e.g. ${a:3:5}, and pattern substitions: ${parameter/pattern/string} ...
Yes we need to upgrade hush.
