The & command is called the "Utility loader". It was placed in by Commodore but strangely never documented (gee... I know of 10-20 other things like that) Anyhow it loads and executes a disk file in DOS ram. On early 1541 disk drives you could also use the "boot clip" to auto load and execute the first file on the disk on powerup. (this feature was removed in ROM revision 5) The command does not have bugs (!), just a weird format for more than 253 bytes of data. -Bryce Nesbitt of the society to port BSD 4.2 to the Timex/Sinclair 1000
