I encountered a few problems with the auto ints on VTI
I used them to make my own timers but it apears that the rate of the timer is completly different on vti and on a ti89 hw2
I don't know if the AMS' programmable timer suffers the same problem but I think that you can exept the programmable timer to work fine but at a fairly different rate than on a real calc
I pass a structure (of roughly 22 bytes) to several functions
you pass the structure by value ?
how can you do that ???
if you pass a pointer (4 bytes) it will be faster, but there will be side effects, beware.
