Hi all,

I'm using stata/se 13 on a 32bit Windows machine now. I find that stata 13
runs much slower than stata 12. 
It took a very long time (longer than a half day) to run the following
syntax using stata/se 13:

foreach var of varlist v1- v50 {
quietly replace `var'="41" if `var'==char(41)
quietly replace `var'="42" if `var'==char(42)
quietly replace `var'="43" if `var'==char(43)
quietly replace `var'="44" if `var'==char(44)
quietly replace `var'="45" if `var'==char(45)
quietly replace `var'="46" if `var'==char(46)
quietly replace `var'="47" if `var'==char(47)
quietly replace `var'="48" if `var'==char(48)
quietly replace `var'="49" if `var'==char(49)
quietly replace `var'="50" if `var'==char(50)
}

However, when I run the above syntax using stata/se 12 on the same machine,
it took much less time (several minutes). 
Do you have any idea about this? Does anyone have similar experiences?
Thanks!

Regards,
Lu Heng
