How do I use a parameter within an OPENQUERY

THIS WORKS
select * from openquery(VFP2,
'
select * from arcust
)




NOW I WANT TO INCOPORATE A PARAMETER - DOES NOT WORK

declare @id varchar(10)
select @id = "54440"

select * from openquery(VFP2,
'
select * from arcust where ccustno=@id
'
)

Any help is appreciated
Thanks
