Message number: 663
Message text: &1 &2: Specific form &3 has wrong interface
Specific routine &V3& has been stored for &V1& &V2&. However the
interface is not defined correctly.
Correct the interface definition of routine &V3&. <ZH>Note that it must
be EXACTLY the same as for sample routine &V4&</>, because internally
the call is explicitly included in the coding.
<ZH>Note:</> The program for checking the interface definition compares
the definition for routine &V3& with the one for sample routine &V4&.
This is also why the interface parameters have to have exactly the same
names. Even the formatting must be identical.
The best solution is to copy sample routine &V4& to the routine you want
to use.
