I don't know of any "official" mechanism to check whether a view exists or not. You could probably try with something like this.

lViewExist = .T.
ON ERROR lViewExist = .F.
use MyView
if not lViewExist
   * create view 
endif

Also, you can look for the view using the the DBC as a table.

use MyDBC
locate for ObjectType = 'View' and ObjectName = 'MyView'
lViewExist = found()
