Steven Lawrance's Operating System (SLOS), also known briefly as Steven Lawrance's Operating Program (SL-OP), was a small interpreted toy operating environment written in {{Tech:BASIC}} for {{Tech:DOS}}. The primary motivation for writing this was to have an environment that supported long file names.

==Scripting Language==
SLOS executes script files having a "exc" file extension in an interpreted manner. Because this interpreter is running within the BASIC interpreter, execution speed is noticeably slow.

==Limitations==
SLOS's scripting environment contains a large list of limitations, and some are expressed in the following list:
*The screen always has a light-blue background with a white foreground
*Conditional expressions are only allowed in a few operations
*Programs get only one number variable and one string variable, which is a huge limitation for all but trivial programs
*Loading and saving data files within a program is limited to saving the program's two variables
*Looping can only be done with the only number variable that you have
