Lotus 1-2-3 is one of the most popular DOS programs available. Many customers use one or another of the several versions on the market. Frequently, they encounter problems of insufficient RAM to process their large spreadsheets.
This appendix discusses how to set up and run Lotus 1-2-3 Release 2.3 (which can use EMS memory), and Lotus 1-2-3 Release 3.1+ (which uses DPMI memory) in a virtual DOS machine in OS/2 V2.0 to handle large spreadsheets.
