Most of the time machine language programs conflict with each other in memory, but I use three great ones simultaneously. First I load Quick! (December 1988), relocated to block 202. Next, Function Key Magician (February 1988) goes in, giving me 16 tailor-made function keys. One of these loads my all-time favorite utility, Triple 64 (April 1985). I can now load and edit three separate 25-block BASIC programs quickly and efficiently. That's a lot of muscle for a 64! Thanks and keep encouraging authors.
