Using the opensource pendant of StarOffice OpenOffice.org is also possible with ODIN until the porters hopefully will have ported the office suite to OS/2 one day.
With the help of VPC (VirtualPC Preview) you don't need booting a Windows machine but if you have one you could do it also. Here is the guide how to use OpenOffice.org (OOo) with ODIN under OS/2 Warp:
1.Download OpenOffice.org
2.Install the package under Windows 9x in VPC or a 'real' Windows 9x machine
3.May be you should use the same directory structure you will use after installation in the OS/2 environment and also I had used a short name.
4.I haven't installed the 'Quickstarter' of OOo
5.After the Installation copy the directory to OS/2 environment.
6.Also copy the files sversion.ini and user60.rdb which you find in a subdirectory of the Windows-directory to the OS/2 environment into the ..ODINApplication Data-directory.
7.Start OpenOffice.org in the ..program-directory of OpenOffice.org with pe soffice.exe
8.Attention: Under Tools / Options / General you should check the option to use the internal OpenOffice.org dialogs otherwise you won't have a possibility to load files
Have fun!
