24 FUNCTION
25
26 AddDataTypes allows you to activate a set of specific DataTypes.
27 This might be necessary if new DataTypes were installed on your
28 system or were not activated on startup.
29
30 INPUTS
31
32 FILES -- The name of the file(s) of the corresponding DataType.
33 QUIET -- Won't output any messages
34 REFRESH -- Refreshes the DataTypes list?
35 LIST -- This will display a list of current DataTypes loaded in
36 memory
37
38 RESULT
39
40 Standard DOS error codes.
