SUMMARY
When using a Quick library in VBDOS.EXE (included with Microsoft Visual Basic for MS-DOS) or QBX.EXE (included with Microsoft Basic PDS for MS-DOS), the Quick library is always placed in conventional memory. If you have expanded memory (as defined in the Lotus/Intel/ Microsoft [LIM] version 4.0 Expanded Memory Specification [EMS]), VBDOS.EXE and QBX.EXE utilize this expanded memory for loaded source code segments that are smaller than 16K; however, Quick libraries are always placed in conventional memory.

Microsoft Visual Basic for MS-DOS, version 1.0 and Microsoft Basic PDS for MS-DOS, versions 7.0 or 7.1 are the only Microsoft Basic products that support expanded memory, so this is not a consideration in earlier versions of the Microsoft Basic Compiler or QuickBasic.

The information in this article is included with the Help file provided with the Standard and Professional Editions of Microsoft Visual Basic for MS-DOS, version 1.0.
