The A-Shell Shared Open Source Library ("SOSLIB") is a collection of common definitions and useful routines. It includes the A-Shell core collection of map, structure, and symbol definitions (ASHINC:, [907,16]), common utility functions (SOSFUNC:, [907,10]), and many useful SBX modules. The library is maintained in an online repository where you can obtain details and downloads. All A-Shell developers are encouraged to visit the repository frequently to browse available routines, obtain the latest updates, and contribute to A-Shell's improvement via bug reports, suggestions, etc. Note that in 2015, the examples from SOSLIB were segregated into their own library, the "EXLIB."
