Hallöchen!

Okay this works:

def generate_type_dublett(visa_type, ctypes_type):
    return visa_type + "=" + ctypes_type + ";" + \
	"ViP" + visa_type[2:] + "=POINTER(" + visa_type + ")"

def generate_type_triplett(visa_type, ctypes_type):
    return generate_type_dublett(visa_type, ctypes_type) + ";" + \
	"ViA" + visa_type[2:] + "=" + "ViP" + visa_type[2:]

exec generate_type_triplett("ViUInt32",  "c_ulong"  )
...


Not very beautiful, though.

Tschö,
Torsten.
