RSX Routines From Magazines

Back in the Good old days of Programs you could type in from Magazines, came a whole range of BASIC programs with Machine Code loaders. A lot of those programs came with a series of Resident System eXtension (RSX), which were accessible from BASIC via the Pipe Command (Shift + @). Programs varied a lot, from Specific Tool developed to carry out a particular operation, to whole Libraries designed to Aid Programmers with their Programming projects. Because there's so many of these programs this list is by no means complete, please feel free to add any relevant programs (try to keep it Alphabetical, I'm using the name used by Magazine, Numbered programs can go first).
