[VFP] WAIT command not fully implemented for VFP dialect

[cpyrgas]

Found this command often used in VFP apps:

WAIT "mymessage" WINDOW AT 10,10 TIMEOUT 1

X# currently reports error XS9002: Parser: unexpected input '"mymessage"'

Guess the UDC command needs to be redefined in the VFP. xh file to support this
