You can specify the buffer size of a RUNB module at runtime (with #32K,  
for example)... is that what you mean? A larger buffer (with larger  
read/writes) will run a bit faster than a smaller buffer, but you can hard  
code it for whatever size you want (within memory restraints, and taking  
into consideration how much RUNB or BASIC09 itself takes... you can get an  
extra 8K for a buffer with RUNB than BASIC09).
