The system ran entirely in RAM, meaning that both the source code and resulting machine code had to be able to fit in memory at the same time. This could be a significant limitation in many situations. Additionally, it did not include the ability to link multiple files together into a single larger program, which put further limits on the sort of programs that could be developed with it. [Eastern Front 1941], which was about 12 to 16k of machine code, required the source to be broken into six modules and then linked together by hand using DOS. Significant effort was needed to ensure that the memory locations in the six files were correct.

The Atari Assembler Editor cartridge was a program used to edit, compile and debug assembly language programs for the Atari 8-bit computers. It was programmed by Kathleen Ann O'Brien of Shepardson Microsystems, Inc., later founding member of OSS, Inc.. It was the first commercially available assembler for the Atari 8-bit computers ever. And yes, it was programmed by a woman. Showing once more, how far ahead of time SMI and OSS were. The program was a two-pass 6502 assembler, in an 8 KB cartridge. With the command __SIZE__, the user gets the info, how much space is free and the command __DOS__, exits the cartridge and jumps into the Disk Operationg System (DOS). There are rumors of a __LOMEM__ command, but AtariWiki couldn't verify this.
