Hi, all,

I needed a routine to take two strings and concatenate them into a single
string. I figured this would be easy. I was wrong.

The working code I finished with looks like this:

/concatstr {
/Addstr exch def
/Mystr exch def
/Newstr Mystr length Addstr length add string def
Mystr Newstr copy length
Newstr exch Addstr putinterval
Newstr

and it works like this:

 (string1 ) (string2 ) concatstr

leaves (string1 string2 ) on the operand stack.

I'm not an experienced ps programmer, and I have to believe I'm missing
something. It CAN'T be that arcane!

or maybe it can... sheesh.

Anybody know a simpler way to do this? Please educate me. Thanks.

That's about it. It would be more efficient, but even more arcane, if
you avoided defining any variable names.  I've seen solutions using
forall as well, but I doubt they are quicker.

No, you've pretty much got the idea. If you will have to do more of this
kind of thing, you would probably find Glenn Reid's book "Thinking in
postscript" very helpful. It's available free as PDF file from <http://www.rightbrain.com/pages/books.html>.

Page 140 shows an example procedure called "concatentate," which works
on both strings and arrays. You might find it interesting or useful.

Best regards.
