LoseThos was an operating system developed by Terry A. Davis. The .sp? file extension identifies C+ source files used by the system and its development tools.
The file contains the text of a C+ program. LoseThos compiles C+ source files statically rather than treating them as scripts interpreted at run time. The format is specific to the LoseThos environment and is not a general-purpose C or C++ source format.
Open a .sp? file in LoseThos using its source-code editing and compilation tools. The C+ compiler can compile the source file within the operating system.
Because the file contains source code, a text editor on another system may be able to display its contents, but it will not provide LoseThos C+ compilation support.
The source can be copied or saved as text, but converting it into C, C++, or another programming language requires manual changes.
To produce a runnable program, compile the C+ source in LoseThos rather than convert the file to another source format.
