The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: The customer has been told that although OS/2 2.0 will use all memory as base memory, DOS programs running under OS/2 will still have a 640K memory barrier by their design. Is this information true? Is it true for Windows applications like WordPerfect for Windows? Solutions: WordPerfect 5.1 for DOS does not have a memory limitation imposed by the operating system it was designed for. WP 5.1 DOS will use whatever amount of conventional memory is available to it. It can also access expanded memory which can be increased or decreased through the session settings for the DOS session that WP is running in. Windows controls the use of memory for a Windows application and allocates extended memory to the application in the amount the application requests. The user can control the amount of memory allocated to the OS/2 Windows session by editing the settings for that session and decreasing or increasing the amount of available memory.
