In bs command, Stata puts a formula in the second set of quotation marks to denote a statistic to bootstrap like

logit y x1 x2
bs "logit y x1 x2" "whatever statistic formula", rep(#)

However, it's kind of strange to me that I cannot wrap up lines use /* */ and it seems that I cannot put space between numeric signs like "_b[_cons] + mean2*_b[x1] + mean3*_b[_x2]" won't work, and I have to get rid of any space like "_b[_cons]+mean2*_b[x1]+mean3*_b[_x2]". Here mean2 and mean3 are defined as scalars. Any input on this? Is that because I use scalar in the quotation mark, or it has to be the case that no wrap-up of the stuff within the second set of quotation marks or the space thing. If so, might be kind of inconvient if I have a long formula for a statistic to bootstrap.
