  • Resolution set to fixed
  • Status changed from new to closed

(In [13498]) Readtable's character-type table (rdtab.ttab) may contain more than 256 elements; size is generally proportional to the largest character code whose syntax-type has been set to something other than constituent. (So users who define cunieform character macros get penalized; better them than the rest of us.) A new function - %SET-CHARACTER-ATTRIBUTE - should be the only thing that modifies rdtab.ttab and only one function references it directly, so it shouldn't be hard to change this if Gilgamesh complains.

Fixes ticket:588.
