SYMPTOMS
Some procedures that compile in Visual Basic version 3.0 generate the following compile-time error message in Visual Basic version 4.0:

Procedure too large



CAUSE
The maximum size of the internal code for an individual procedure in Visual Basic version 3.0 is 64K bytes. Microsoft Visual Basic version 4.0 for Windows uses Microsoft Visual Basic for Applications, which generates more generic internal code than does Microsoft Visual Basic version 3.0. This generic code allows for compatibility with a wider range of processors. This makes the internal code larger, so it can cause very large procedures to exceed the 64K limit and fail to compile.



WORKAROUND
Split the large procedure into two or more smaller procedures.



STATUS
This behavior is by design.
