36-bit Systems
Radix-50 in 36-bit systems was commonly used in symbol tables for assemblers or compilers which supported 6-character symbol names. This left 4 bits to encode properties of the symbol.
Radix-50 was not normally used in 36-bit systems for encoding ordinary character strings; file names were normally encoded as six six-bit characters and full ASCII strings as five 7-bit characters and 1 unused bit per 36-bit word.

Famous quotes containing the word systems:
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
