1. you forgot the RET at the very end.  before the .end you need a ret
which tells the program to go back to where it was before the program
was run (end the program), otherwise after the _ILine command the calc
still proccesses insturctions after that in memory, they are random so
it will crash the calc.
2. to print to the graph screen copy  info to $c9fa, instead of $fc00,
you can't use _ILine though, just PutSprite type routines.
