<p><b>New page</b></p><div>'''RADIX-50''' is a coding system much used by [[Digital Equipment Corporation|DEC]], particularly in [[PDP-11]]'s, to hold alphanumeric data in a fairly space-minimal form. It could hold 3 [[character]]s in a single 16-[[bit]] [[word]]. Individual characters were not stored in separate bit fields within the word; rather, a multiplication and addition process was used to combine them.<br />

The character set supported included the characters ' ' (encoded as 0), '$' (27.), '.'
