Apple IIe boots DOS 3.3, loads Integer Basic, nothing works ?

[mfe@fast.net]

I just bought my first Apple IIe.... could never afford one in the early 80's, so now I have one.  So... I am not 
real familiar with these machines.... The person I bought the IIe from gave me a disk, and when I boot it, it say 
its Apple Dos 3.3, and then appears to load Integer Basic into the "Language Card" !  Well, nothing then 
works....  for example,

 ] catalog     gives syntax error
 
 ] 10 print "hello"
 ] run         gives syntax error

 ] 10 print "hello"
 ] list     gives syntax error

EVERYTHING seems to be a syntax error.  Whats going on ???  Did this disk overwrite Applesoft basic with 
Integer basic, and now I'm hosed ???  Anybody got a ProDos boot disc I can buy ???  Why is everything a 
syntax error ???
