A-Shell includes many sample programs, common routines and mappings, contributed programs and miscellaneous files that are “community property”–i.e., they are un-owned and unlicensed parts of A-Shell that developers may use and/or contribute.


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.

The A-Shell Example Library (“EXLIB”) is a collection of mostly small standalone example programs designed to illustrate or test particular A-Shell features. They are organized into PPNs in the [908,*] range, with each PPN focusing on a particular area. The library is maintained in an online repository where you can access and view individual files or download the entire set.
