make ord() result unsigned int; add asc() which is:

Browse Source 
• not designed to be emitted, only used in comparisons with
  other asc() results
• on EBCDIC platforms, the mapping of an EBCDIC octet to their
  corresponding ASCII or Unicode/UCS-4 codepoint or, if there
  is no mapping, a distinct value above all valid Unicode codepoints
• on nōn-EBCDIC platforms, just the identity mapping of the input
  octet into their ord() value

Intended use are ASCII-ish character ops, including ranges (“A-Z”),
mapping from those to the corresponding digit offset, and sorting
of things in an ASCIIbetical way
