Hello,

i wonder if there is a way to do string concatenation
within xplor?

i have trouble with the following:

evaluate ($dir = "./final/isomer1")
! this seems to work so far, double quoting prevents
! parsing of string as mathematical expression
loop
.....
.....
.....
     evaluate ($n = $n + 1)
     write coordinates output=@$dir/struct$n.pdb end
end of loop

i know that @$dir/struct$n.pdb is not a correct
xplor statement, but i just wonder how to do 
calculate the path 'on the go', for that i would need
simple string concatenation, but all the examples i have seen so far interpret 
the string "a/b"
as division of a by b

I appreciate any response.

Evgeny.
