 I am most familiar with F-PC for the MS-DOS world.  Here's how F-PC 
 gets around the segmentation limits: 

       Code Segment = Data Segment = Variables and CODE words 
       Extra Segment =               Each colon definition starts on a 
                                      paragraph boundary, and NEST sets 
                                      ES to the start of the current 
                                      word. 
       Other =                       The names for the words are kept 
                                      in a separate segment that isn't 
                                      dedicated to any particular 
                                      segmentation register. 
       Stack Segment =               In plain-vanilla F-PC, it's set to 
                                      the same as the Code and Data 
                                      segments.  It's relatively easy to 
                                      separate out as another segment; 
                                      usually, there aren't that many 
                                      tasks, and the stacks are small, 
                                      but I run many multiple threads 
                                      under DESQview, and DESQview 
                                      seems to require huge stacks. 

 Hope this gives you some ideas!
