To be fair, what I gave there as an example is blocking if there isn't 
a character to read, one really should make use of the _os9 i$getstt 
call as mentioned in a previous message this morning to acertain that 
there is indeed a character or more to read, thereby giving you the 
opportunity to do something else if the buffer is empty.  If yopu 
don't have anything else for it to do, then make sleep calls, thereby 
unloading the cpu for other stuff, in a loop that wakes up to see if 
anythings been typed while napping.
