Some small confusion here. The global macro in question is called S_DATE
and thus is referenced by $S_DATE: in fact it is usually better quoted
as "$S_DATE" . It is an old-style equivalent of c(current_date). 

The strict answer to Raphael's question is that you can re-define this
macro to be  without spaces, but it is better to display a copy that
does not contain the spaces. 

As Svend's suggestion implies, this can be done via 

subinstr("$S_DATE", " ", "", .)

The macro $_DATE displays current as 20 Jun 2008. I am looking for a
simply way to remove the spaces.
That is, 20Jun2008.

I did not succeed with $_DATE, but with c(current_date) it is:
 
    . local z = subinstr(c(current_date) , " " , "" , .)
    . display "`z'"
    20Jun2008
