Originally released in 1988 for OS/2 1.x as a commercially supported clone of the Berkeley C shell alongside 20 other utilities that made using the shell and porting Berkeley C script files to OS/2 easier. The Berkeley C shell is a shell that was originally supplied as an alternative shell for the Berkeley Software Distribution (BSD), it had a batch language that was much more C like than what the traditional UNIX shells offered, the original C Shell however uses a slow interpreter for executing its batch files while the Hamilton version actually uses a built-in compiler.
The original release for OS/2 1.x allows you to use 64k heaps for command lines and pipes, meaning that you can have command lines considerably longer than the 256-character limit of the CMD.EXE.
