Shige:
-forvalues- expects a range not a list. If you want to loop over a list
you should use -foreach-. See -help forvalues- and -help foreach- for
more information. Correct code would be:

local varlist waglevl_f1989 waglevl_f1991 waglevl_f1993 /*
           */ waglevl_f1997 waglevl_f2000 waglevl_m1989 /*
           */ waglevl_m1991 waglevl_m1993 waglevl_m1997 /*
           */ waglevl_m2000

foreach var of varlist `varlist' {
	replace waglevl_f`n' = . if waglevl_f`n'<0
	replace waglevl_m`n' = . if waglevl_m`n'<0		
}
