Speaking Stata: How to face lists with fortitude

Nicholas Cox

Stata Journal, 2002, vol. 2, issue 2, 202-222

Abstract: Three commands in official Stata, foreach, forvalues, and for, provide structures for cycling through lists of values (variable names, numbers, arbitrary text) and repeating commands using members of those lists in turn. All these commands may be used interactively, and none is restricted to use in Stata programs.They are explained and compared in some detail with a variety of examples.In addition,a self-contained exposition is given on local macros, understanding of which is needed for use of foreach and forvalues.
