Re: st: Setting a variable's value equal to the name of another variable

[Nick Cox <njcoxstata@gmail.com>]

Quite so. -IPO- is numeric and you are trying to force a string value
upon it. That won't work.

Note that the loop over observations is redundant here; that is what
Stata does any way.

It seems that you want some sort of string tag or flag. Perhaps this
is closer to what you want.

gen flag = ""

foreach var of varlist Listedness1-Listedness371 {
      replace flag = "`var'" if `var' ==1 & `var'[_n-1]==0 & IPO==1 &
IPO[_n-1] == 0
}

This will, just as your code would if it were legal, overwrite any
result for an earlier -Listedness- variable. All you will see is the
last change made.
