Algol 68 was actually slightly different. There were two separate alphabets: one used for names of constants, variables, routines and labels, where spaces were ignored, and a different one used for type names (called “modes”) and reserved words, where spaces were significant.

The convention was to use lowercase for the former and uppercase for the latter.
