DOCUMENT:Q66308 31-OCT-1999 [utilities] TITLE :PWB's Use of Expanded Memory PRODUCT :Microsoft Programming Utilities PROD/VER:MS-DOS:1.0,1.1 OPER/SYS: KEYWORDS:kb16bitonly ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Programmer's Workbench for MS-DOS, versions 1.0, 1.1 ------------------------------------------------------------------------------- The MS-DOS version of the Programmer's WorkBench (PWB) will utilize expanded memory to swap its own segment overlays if it detects that expanded memory is available in the system. When PWB needs a new overlay, the existing overlay in memory is first copied into expanded memory. If there is not enough room in expanded memory to copy the overlay, the least recently used overlay is discarded to make room for it. This scheme allows most overlays to be read from expanded memory instead of from disk. Note that this is the only method by which PWB will take advantage of available expanded memory, and that PWB versions 1.0 and 1.1 have no internal provisions to make use of extended memory in any way.
