Use -display- to check the contents of your locals. Also, notice that local
doesn't take a varlist, it takes an expression; so, local doesn't expand the
varlist for your line "local tvars prefix_*" :
*******!
sysuse auto, clear
rename mpg prefix_mpg
rename price prefix_price
rename weight prefix_weight
rename foreign prefix_foreign
*****
local tvars prefix_*
di "`tvars'" // doesn't work
*****
ds prefix_*
local tvars `r(varlist)'
di "`tvars'"
token `tvars'
di "`1'"
local regressand `1'
mac shift
local regressors `*'
di "`regressors'"
**
regress `regressand' `regressors'
di "`e(cmdline)'"
*******!
