From: greenwillow on 16 Jul 2010 15:13 I have more than 30 variables. I need to select out the observations which have at least one variable larger than 3(cutoff point). I know I can write as if var1>3 or var2>3 or.................or var30>3; to select out the observations. Is there an easier way to do this?

Try max() function: if max(of var1-var10) > 3; HTH Ya From: greenwillow on 16 Jul 2010 15:17 thank you Ya. But what can I do if the variable names doesn't have a common index. The variables names are more like aa1bb, aa2bb, .... On Jul 16, 2:15 pm, Ya wrote:> On Jul 16, 12:13 pm, greenwillow wrote: > > > I have more than 30 variables.
