st: Re: how to add 23 in each row of a variable

[Martin Weiss <mw.stlist@googlemail.com>]

-replace number=number+23-

is the easiest solution. -replace- operates on the "vector" of observations 
for "number". If you are desperate for the -while- loop, make sure you step 
up the index, e.g. add -loc ++i - as the last statement before the closing 
brace...
