Yep, this is what I said in my last posting -- OS9's file lookup does not  
benefit from all the speed tuning lavished on Shell+.
 
Even in Linux, in a C program you can't say
    fopen("$HOME/file", ...)
since the OS file opener doesn't do ENV variables like HOME.
 
As for looking to see whether subr modules are already in RAM, I swear that  
Basic09 was really stupid in that regard.  One reason I was glad to get  away 
from any serious BASIC09 programming, was the behavior (or lack of it)  around 
those subr modules that had to be found, to run graphics or non-blocking  
character input (GFX, INKEY).  RUNB especially couldn't figure out what to  do to 
find them.  I quit fighting and went to C.  --Mike K.
