Dear Simon,
In message CAPnjgZ3SXdKaKmYCw=Q0w-JGhghAPVhwHdtG5q2dNEMNiY60Xg@mail.gmail.com you wrote:
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
I don't get it. The equivalent to "${a}${b}" would be
setexpr c "*10*100"which is even simpler?
I don't see how that works. The *10 thing in my example reads a string out of address 10.
Regards, Simon
