[A83] Re: allocating uninitialized memory? + _insertmem
And since I made up the names for FREE_MEM_START and FREE_MEM_END, then
aren't in ion.inc or ti83plusasm.inc or anything - so here you go:
#ifdef TI83P
FREE_MEM_START .equ $9824
FREE_MEM_END .equ $9828
#else
FREE_MEM_START .equ $930D
FREE_MEM_END .equ $9311
#endif
