Some of the examples go against a recommendation within the API documentation.

[Supermath101]

The recommendation is embedded within the codebase here:

Adafruit_CircuitPython_PIOASM/adafruit_pioasm.py

Lines 556 to 558 in cf1dd1e

	In new code, prefer to use the `Program` class so that the extra arguments
	such as the details about side-set pins can be easily passsed to the
	``StateMachine`` constructor."""

It's eventually rendered as documentation here: https://docs.circuitpython.org/projects/pioasm/en/latest/api.html#adafruit_pioasm.assemble

Most examples embedded within this repo use the deprecated approach, but I did see at least one that uses the recommended approach:

Adafruit_CircuitPython_PIOASM/examples/pioasm_7seg.py

Lines 48 to 52 in cf1dd1e

	_program = adafruit_pioasm.Program(
	"""
	out pins, 14 ; set the pins to their new state
	"""
	)
