Ah, got it. This requires your "[PATCH 10/10] setexpr: Add support
for strings" first...
But then... should there not be some '.s' size specification
somewhere?

/o\ ah, OK, that makes sense. So setexpr can dereference strings.
I didn't know about that, I thouth the resulting string would be
"*10*100".

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

What is the purpose of + operator on strings?
Can't we use setenv "${a}${b}" ?
Add support for dealing with string operands, including reading a string
from memory into an environment variable and concatenating two strings.
