st: RE: Fwd: foreach loop for generating missing variables

["Jesper Lindhardsen" <JESLIN01@geh.regionh.dk>]

Hi Andreas

This should work, although a crude method:

forvalues val=100/894{
	capture gen x`val'=.
}

I must admit that I think your reason(s) for doing this should be
re-evaluated ;-)

HTH,

Jesper

Subject: st: Fwd: foreach loop for generating missing variables

Dear Stata experts :  PLease help!

I have a series of variables "x100 ... x894" in which many of these
variables are missing. e.g. x240 does not exist

I would like to create these missing variables which contain zero for
all
observations.

how do i create these missing variables ?

i have tried writing a loop

!foreach x of newlist  x100- x894{
!gen `x=92 =3D0
!}

but keep getting an error as some these variables already exist.


thank you in advance,
Andreas
