You're getting slightly too esoteric for this 1980's COBOL programmer 😂 

BTW: Have you ever seen a Hungarian mainframe manufactured by a state run company called Videoton which ripped off the Bull Mitre O/S and a german COBOL compiler.

It was called the VT6000 and we had the only one in the west because both MI5 and Hungarian intelligence were trying to recruit my Dad as a spy. He got favours from both sides 😂 

Try using printed instruction manuals written in Hungarian, French and German 😱 

That was my introduction to serious computing after starting off with a Dragon 32, Commodore PET and then an IBM XT.
