OS is a member of the APLTree library. The library is a collection of classes etc. that aim to support the Dyalog APL programmer. Search GitHub for "apltree" and you will find solutions to many every-day problems Dyalog APL programmers might have to solve.

This class offers methods that return the same result under Windows, Linux (without the PI) and Mac OS.

Examples are GetPID and KillPID.

Exceptions are the functions ShellExecute (Linux/Mac only) and WinExecute (Windows only). They perform very similar tasks but with very different parameters and results, so they were separated.

Shared Methods:
