请问怎么把几条命令连续执行100次。比如我现在想让下面的一堆命令重复执行100次。这种能写个循环吗，求指点，谢谢大佬们！

-----------------------------
use "C:\Users\list.dta", clear
sample 6, count
merge 1:m id using "C:\Users\实验组.dta"
replace treat=0 if _merge==2
xi:reg  y c.treat##c.time   ,robust
parmest,format (estimate %8.2f p %8.3f) saving("temp.dta", replace)
use "temp.dta", clear
keep if parm=="c.treat#c.time"
append using "C:\Users\PARM.dta"
save "C:\Users\PARM.dta", replace
