Hello all,
 
Could somebody please point me to a FULL and COMPLETE explanation of the [expr] object.  The only expression that I've been successful using is:
 
[expr 1-$f1] (or something similar).
 
However, I know that MAX/MSP's [expr] object supports If > Then statements etc...  Before the [expr] object become useful to anybody, there needs to be a full explanation of its usage, syntax, and methods.
 
Many thanks,
Dave Sabine
