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 Operating System (DOS). There are rumors of a __LOMEM__ command, but AtariWiki couldn't verify this.

!!Hint
If the user intends to resize the used memory, the command: 'LOMEM xxxx' must be the very first command after booting. Please see page 7 in the manual for further info. Otherwise the user will get an error:\\
[{Image src='LOMEM-SIZE-2.png' width=606 height=317 }]
LOMEM command - correct use\\
\\
[{Image src='LOMEM-SIZE-1.png' width=611 height=296 }]
LOMEM command - incorrect use\\
\\
Thanks to Sijmen Schouten for the hint. :-)
