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.
