return-in-program (PORT041)

Fix is always available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does

Checks for use of return statement inside a program body, as allowed by some compilers. Suggests to replace it with stop.

Why is this bad?

It is non-standard and not portable.

Example

program test
  return
end program test

Use instead:

program test
  stop
end program test
