Subject:   Re: how-to stop datasteps if nobs=0 in macro

You have had some good suggestions.

A simple tool, useful in such situations, is the CANCEL option of the RUN statement. Basically, the idea is to code

run &cancelswitch;

so that a step can be toggled on or off by manipulating the value of the macrovariable (to blank or "CANCEL").
