Closed Issue: Some VFP internal functions accept "plural" of their name as a valid function name (VFP 9 help) [30547]

This is probably not so important but it is a fact which is not mentioned in the help.
 
I've found following functions is possible to call via "plural" form of their name:
 
FIELDS() is allowed instead of FIELD()
FILES() is allowed instead of FILE()
MESSAGES() is allowed instead of MESSAGE()
POPUPS() is allowed instead of POPUP()
 
The question is if to mention this possibility in the VFP help...
