Well, that should not surprise us; we said that the varlist was required in the syntax command, so when we tried myprog without explicitly specifying a varlist, Stata complained. A program can contain any Stata command, but certain Stata commands are of special interest to program writers; see the Programming heading in the subject table of contents in the Stata Index. Commands have a consistent and predictable syntax, whether the command fits a model, produces descriptive statistics, or performs a data management task. They tell Stata to do something: summarize Remarks and examples capture is useful in do-files and programs because their execution terminates when a command issues a nonzero return code. See [P] trace for information on debugging programs. Some Stata users live productive lives without ever programming Stata. I wrote printgraph such that graph type, y-variable and x-variable are passed to it as arguments. Stata programming is an advanced topic. Also do-files and programs can be made to respond appropriately to any situation by conditioning their remaining actions on the contents of the Syntax are the rules of a language. This syntax allows you to control what part of the data set the command acts on, modify what the command does, and more. Specifically, a program represents a Stata subroutine that " allows [users] to define a chunk of code in one place and run it repeatedly" ("Programming in Stata," 2007). A Stata program is essentially a user-defined command that allows you to encapsulate a sequence of Stata commands into a single, reusable command. This colloquialism is accurate, but the term "program" also has a particular meaning within Stata. On the other hand, programming Stata is not difficult—at least if the problem is not difficult—and Stata’s programmability is one of its best features.

In this case not any syntax would do; only a list of at least one of the variables in Stata’s memory. Stata also have syntax and once you learn the stata command syntax then creating a commmand becomes an easy task. As you learn more commands in Stata, you can save yourself time by typing these commands directly into the Command window. After all, you do not need to know how to program Stata to import data, create new variables, and fit models. 2. wuu xc61 ps99vtt mk8 uajdd lb2jnt zpw10y j8lph6 88jm r821qgk
