Great Runes n.
Uppercase-only text or display messages. Some archaic operating systems still emit these. See also runes, smash case, fold case.
There is a widespread legend (repeated by earlier versions of this entry, though tagged as folklore) that the uppercase-only support of various old character codes and I/O equipment was chosen by a religious person in a position of power at the Teletype Company because supporting both upper and lower cases was too expensive and supporting lower case only would have made it impossible to spell `God' correctly. Not true; the upper-case interpretation of teleprinter codes was well established by 1870, long before Teletype was even founded.
