Problem

Symptoms: The customer needs exact memory requirements for the WP program. The customer receives "Insufficient Memory" error messages all the time and needs to know exactly how much RAM WP needs to run at its full capacity and how much expanded memory it can utilize. Solutions: We went over the non-proprietary information regarding memory usage. She is trying to make a dynamic memory allocation algorithm into a concrete and consistent one. We reviewed the following: 1. 384K is the minimum amount of conventional memory required to execute WP. 2. When a keyboard is selected the total size of that is used by conventional memory so it is always present. This takes up additional conventional memory and can reduce the amount of memory left for printing, previewing, etc. 3. If the customer is getting out of memory error messages while doing one of these things, then they should try deselecting the keyboard and see if that makes a difference. 4. An undetermined amount of the .PRS file is permanently stored in conventional memory so the document can be formatted correctly. This can reduce the amount of memory left for other features if you have a large .PRS file. It is suggested that large .PRS files are broken into several smaller ones. 5. The following features use expanded memory: Sort, Generate, Virtual files, Spell, Rasterizing graphics 6. If enough expanded memory is available, you can load the WP.FIL into it through the startup option /R. 7. I verified that WP.EXE cannot be executed or run from expanded memory. 8. I also verified that there were no major changes in the 06/29/90 and 08/20/90 releases as far as memory is concerned.
