Dear All,

I'd like to know how to generate a macro out of a numerical variable. For example, I have a variable A that includes 200 values, I want to generate a macro X that contains all the values that variable A has so that I can do something like:

foreach x of local X {

qreg ... , q(x)

}
You should probably use Nick Cox's -vallist- command (type -ssc describe vallist- to find out more). Your program might be as follows:

vallist A
local vals "`r(list)'"
foreach X of numlist `vals' {
qreg ... , q(x)
}

I hope this helps.

Roger
