0012FE1C   0012FF60 0012FF54
scanString n	    r

(all variable pointers are in the 0012F??? range)

Unhandled exception at 0x004182c0 in Combinations and
Permutations.exe: 
0xC0000005: Access violation writing location 0xe7430e45.

Unhandled exception at 0x004182cc in Combinations and
Permutations.exe: 0xC000001E:  An attempt was made to execute an
invalid lock sequence.
