This is a small 10-Liner that I wrote which creates some RSXs which substitutes for those on BASIC 1.1, which is not available on 464 machines. Its purpose is to ensure compatibility with the 464 in most listings that are printed in magazines. It emulates the following commands:
Unfortunately, the |FILL command is not emulated here. However, if you cannot get a BASIC listing to work, then you could use these RSXs instead. When you run the program, wait for a moment, and you will get the message, "BASIC, Help or Save (B/H/S)?." Enter H, and you will see the built-in instructions listing how to use all the RSXs. Entering S will save a binary file which you can use in your listing to initialise the RSXs without running this program first.
