You should've been using the checksums provided next to each listing.  The
earlier (up to early 1986?) Key Perfect codes would narrow errors down to
within some group of lines IIRC, but the later codes worked on a
line-by-line basis and would let you spot errors fairly quickly.  For those
later codes (don't recall offhand what they called it), they even included a
program to generate the codes as you typed in the program.  I modified this
to dump codes for a program already in memory; it wasn't a particularly big
mod, but it was useful for a high-school student with no spending money. :-)

Key Perfect is now a free download from nibblemagazine.com.  If you want a
copy of the other verifier, let me know and I'll see if I can dig it up.  (I
should still have it on a floppy, if it's not already stashed on my GS's
hard drive somewhere.)
