 Imagine that you wanted the program to be called h instead of hello:  . program h 1. display "Hello, world" 2. end . h  Surprisingly, this brings up the introduction to Stata’s help system. Th reason is that the letter h is a shortcut for the Stata command help, which is an official Stata command. Stata only searches for programs when it has not found an internal Stata command with the specified name. For this reason, you should never define a program with the same name as an official command. In order to ascertain whether a command with a given name already exists, enter the name or enter which commandname. If Stata replies with “unrecognized command”, you may use the name for your program. Imagine that you wanted the program to be called q instead of hello:  . program q 1. display "Hello, world" 2. end . q  Surprisingly, this displays the settings of various Stata parameters. The reason is that the letter q is a shortcut for the Stata command query, which is a “built-in” Stata command. Stata only searches for programs when it has not found a built-in Stata command with the specified name. For this reason, you should never define a program with the same name as a built-in command. In order to ascertain whether a command with a given name already exists, enter which commandname. If Stata does not reply with “built-in command: commandname”, you may use the name for your program.
