Toby,
You're right, you wouldn't win any prizes with that explanation but it gets the point across. Thanks...

Clinton ,
It gets complicated, well for me to explain in a few short sentences it
does. Think about it like this %str and %nrstr quote the value at compile
time. Which means that the value that is stored in the symbol tables is
masked. When quoting macro vars values the characters that are quoted get
transformed to a non printable characeter. All %put _User_ does is a dump
from this table to the log. Hence you see the slashes as blanks (they are
still nonprintable characters). The symbol tables just hold text values and
rermember %put _User_ only asks for a dump of this to the log, not a dump
and a full resolution of the characters in it. The macro quoting and
unquoting and replacing of nonprintable characters for prinitng purposes
gets done outside of the symbol tables.
%put &Test3
The value from the resolution of test3 is still quoted, so for compile and
exectution time they are masked from the macro facility, but for printing
purposes SAS will replace the nonprintable chars with the correct ones.
This is probably a really bad explaination I will have to work on it some
more.

All,
Interesting... %PUT of the individual variable works but _all_ and _user_
does not in my environment (EG 3.0 talking to 9.1.3 on Solaris). Any
rational reason why not?
11 %let slashes = %str(//test/test2) ;
12 %let test3 = &slashes./test4 ;
13 %put %unquote(&slashes);
//test/test2
14 %put %unquote(&test3);
//test/test2/test4

Jiann ,
When you reference a the macros in a %put statement they dont need to be
unquoted:
77 %let slashes = %str(//test/test2) ;
278 %let test3 = &slashes./test4 ;
279
280 %put &test3 ;
//test/test2/test4
281 %put &Slashes ;
//test/test2

Hans:
Use %unquote to restore the significance of symbols as the following
shows.
60 %let slashes = %str(//test/test2) ;
61 %let test3 = &slashes./test4 ;
62 %put %unquote(&slashes);
//test/test2
63 %put %unquote(&test3);
//test/test2/test4

Dear Listeners,
I stumbled over an irritating macro var resolution, using EG:
%let slashes = %str(//test/test2) ;
%let test3 = &slashes./test4 ;
%put _all_ ;
GLOBAL SLASHES test test2
GLOBAL TEST3 test test2 /test4
Slashes are not correctly reproduced (and brackets as well ?), when
the
string is enclosed in %str()...
...strange...
Any ideas ?
Cheers,
Hans
