I often do something like this program example version 10.1 args factor garbage if "`factor'" == "" | "`garbage'" != "" { error 198 } You can approach this in other ways, but I find this to be among the most transparent. Nick n.j.cox@durham.ac.uk Nathan Danneman I have written a program, which utilizes the args command. The program analyzes regression results, and requires the user to input a single constant. Is there a way to generate an error message if the user inputs an incorrect number of arguments (either none, or more than one)? Here is what the program looks like... capture program drop example program example version 10.1 args factor ** I would like to input a line here that would do something like (if number of args != 1, then error "wrong number of arguments") ... ... end * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
