PRB: Procedure too Large Error When Compiling in VB 4.0

 Last reviewed: October 30, 1995
Article ID: Q129897
The information in this article applies to:
  • Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

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.
