running program inside a loop in Stata -

i trying run program inside loop, getting

-break-- r(1); 

here script:

 clear     forvalues i=1/5{     sysuse auto if rep78==`i'     capture program drop testpro     program define testpro,eclass     preserve       tabstat price mpg headroom,stat(mean) save     mat avg=r(stattotal)     ereturn post avg     restore      end     }     --break--     r(1);      end of do-file      --break--     r(1); 

any in regard highly appreciated.

there several issues here. one, can't sysuse if clause, unlike use.

there's no need re-define program each iteration of loop. define it, loop.

i not sure why need program, matter of taste or perhaps merely pedagogical example.

the command estadd in code below part of estout suite scc.

clear  capture program drop testpro program define testpro, eclass tabstat price mpg headroom, stat(mean) save quietly estadd matrix avg = r(stattotal), replace end  forvalues i=1/5 {     sysuse auto, clear     keep if rep78==`i'     testpro     matrix list e(avg) }
