At line 6 changed one line
Atari originally licensed the 6502-assembler code for Microsoft BASIC, which was about 9k in size. The Atari design limited cartridges to 8k, and the Atari programmers struggled to cut the MS code down enough to fit in a cart. That was bad enough of its own, but they really wanted to add additional instructions to take advantage of the Atari's graphics and sound as well. Eventually they gave up and went looking for a 3rd party to do it for them, and eventually chose Shepardson Microsystems.

At line 8 changed one line
Shepardson, or SMI for short, won the contract. They proposed cutting some features and adding others to provide access to the capabilities of the new machine. The result required about 10k, so to cross the remaining gap to 8k, some of the core libraries were moved out of the language and into the operating system ROMs. This had the side-effect of allowing any other language on the Atari to use these routines as well.
Shepardson Microsystems Inc, or SMI for short, won the contract. They proposed a simplified syntax and the cutting of a number of rarely-used features, leaving more room for new commands for graphics and sound. Even then, the result required about 10k, so to cross the remaining gap to 8k, some of the core libraries were moved out of the language and into the operating system ROMs. This had the side-effect of allowing any other language on the Atari to use these routines as well.
