It looks like a bug with the VFP command parser:

"HELP ID nContextID" is a legitimate syntax for the HELP command.

It looks like the parser is reading "HELP ID" then after that it's looking for a numeric ID number, rather than checking for the possible presence of "()" that would indicate the ID() function. Basically, they named an internal function the same as a reserved word.

So, the CodePlex help file won't help this issue.
