    Braces must be specified with foreach, and

        1.  the open brace must appear on the same line as the foreach;

        2.  nothing may follow the open brace except, of course, comments;
            the first command to be executed must appear on a new line;

        3.  the close brace must appear on a line by itself.

Subject: Re: st: Scaling of variables

Hi

I tried it but get the following error:

foreach v of var earnings lt dltt {gen 'v'_at = 'v'/at}
program error:  code follows on the same line as open brace
r(198);

earnings, lt, dltt are some of the variables.

Thanks again
