Unless you are working with Stata 6 or earlier, -forval- is easier than -while- here, and indeed almost everywhere else. Steven's code could thus go forval i=1/100 { scatter data301 time if countrygroup==`i' graph export group`i'.tif, replace } In terms of the original question, rather more general approaches to looping over groups are indicated in FAQ Making foreach go through all values of a variable 8/05 Is there a way to tell Stata to try all values of a particular variable in a foreach statement without specifying them? http://www.stata.com/support/faqs/data/foreach.html Nick n.j.cox@durham.ac.uk Steven Proud Depending on how your countrygroups are defined, I've assumed that they're 1 to 100 for instance. local i=1 while `i'<=100 { scatter data301 time if countrygroup==`i' graph export group`i'.tif, replace local i=`i'+1 } This saves a graph as a tif file for all 100 country groups.
