I am a new guy here, but pretty old everywhere else.
I started computing on a DEC PDP-8. We called them Minicomputers. It was the size of a refrigerator, and had 32k of core memory.
I recently opened a CMD window in Windows 8.1 and typed in "edlin file1"
Windows 8.1 tells me " 'edlin' is not recognized as an internal or external command, operable program or batch file."
I am so screwed.
