I would think that task-switching during NEXT would create too high of an 
overhead. Seems to me that switching during : or ; would be more 
reasonable.  However, I would still prefer PAUSE and similar for more 
control.
 
However, I would like to be able to have a multitasking Forth which can 
handle having more than one file open at a time; this is with a 
single-user operating system (namely Prodos, but MS-DOS or CP/M are also 
single-user similarly). How in tarnation would you keep track of the open 
files?
 
The big problem is that I want two users to be able to write in the same 
file at the same time; so I need record-locking but dont know how to 
implement it. Any thoughts?
 
By the way, I would say that there are SOME of us STILL using CP/M out 
here... too bad the F83 isnt Z80 code though. Better yet, somebody otta 
write a decent F83 for ZCPR3.
