The last time I checked my Applesoft source code (unofficial, produced
by Southwestern Data Systems) "fre" doesn't check it's arguments.
BUT!!!! Prodos, DOES change this.  (The same way PRODOS intercepts
"hgr" commands to handle memory allocation.)

Key point: What fre() you get depends on what DOS you use.
