Programs are defined and manipulated using the -program- command.

To list all defined programs, try:

To examine a program, try:

program list foo

The following is the declaration of a simple program that takes two arguments.

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