Stata Programs

Reusable functions can be defined in the Stata programming language as programs.

Programs are typically saved to and distributed in ado files.

Contents

Definition

Stata programs are defined using the program command.

program foo
  args a b
  if "`b'"=="" {
    di "Expected 2 arguments (got 1)"
    exit
  }
  gen `a'=`b'
end

To list all defined programs, try:

program dir

To examine a program, try:

program list foo

Use program list _all to list the contents of all programs.

To delete a program, try:

program drop foo

Use program drop _all to delete all programs and program drop _allado to delete all programs that were loaded from ado files.
