The manual's compatibility box for this call, word for word.

Yes/no fields from the YAML extraction (not in the manual's words):

ND-100	ND-500	User programs	RT programs	System programs
Yes	No	No	No	No

Disagreement

The manual box says ND-100 and ND-500, but the yes/no fields say ND-100 = Yes, ND-500 = No. The manual box is the source.
