You can achieve what you want with a combination
of -unab- and extended macro functions, see the 
example below and -help unab- and -help macrolists-

hope this helps,
Maarten

*----------- begin example -------------
sysuse auto, clear

/* create variables rep1 - rep5 */
tab rep78, gen(rep)


/* create list of all variables */
/* whose first three characters */
/* are "rep"                    */
unab vars: rep*

di "`vars'"

/* create a local containing    */
/* the variables you want to    */
/* exclude */
local not "rep78"

/* exclude those variable from  */
/* your list */
local vars: list vars - not
di "`vars'"
*------------ end example --------------
