Possibly.  I have passed by value on numerous occasions, but you can't do 
math 'in' the call.  Either before or in the subroutine has always worked if 
my wet ram can be trusted at 75.  If it had been a problem I'm sure I would 
have remembered it.  That may be something that since it could be coded 
around, wasn't worth the extra bytes to handle it in the call.  This basic, 
FWIW was from what I've read back in the foggy past, modeled more or less on 
True Basic, and what little TB code I wanted to use was pretty easily 
adapted, although the biggest piece I re-wrote in C as it needed the C's math 
precision of about 17 digits.  B09's 5 byte representation of a real sorta 
gets wonky when you want minute accuracy over nearly 6700 years. :)
