When a "single statement" can be called a program?

[POOJA_J]

I read in a book, a single statement as well as multiple statements can be called as a program.

Plz explain what can be an example of a single statement which itself can be called a program?

Trivial example.  Create a file named find_sas_version.sas that contains:

%put &sysvlong=;

Run it.

A sas program contains SAS statements.  Typically multiple statements that create steps etc.  But a SAS program could have a single statement, such as any global statement.

For example, a program with single title statement is still a program, and it would run.

title "hello" ;
