• 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
• make fast character classes even faster by removing the C_SUBOP2 hack
in favour of a separate seldom-used ksh_issubop2 macro (which also
makes ctype() side-effect-safe) which is a slower class (no change there)
• optimise cases of ksh_isalphx followed by a ksh_isalnux loop
(used parsing variable names)
• remove a misleading comment in initctypes() about \0 from pdksh
• rename C_ALPHA to C_ALPHX to make it more clear the underscore is included
• sprinkle a few ord() in there
• add new ksh_isalpha() which tests for [A-Za-z] (slow character class)
• there is no '_:\' drive on OS/2 (which inspired the whole changeset)
related to that:
• while AT&T ksh may do it, POSIX says nothing about allowing
declaration commands only without vars and redirections, and
“without vars” especially seems against which commands they are
• fix relationship between forwarders and real declaration commands
• clean up c_builtin vs shcomexec mess
Also, re-run “make repool” with a fixed src/scripts/stringpool.sh,v 1.3
mksh_sdirsep() returned a position of a more far directory separator
if '/' and '\' were mixed.
And mksh_sdirsep() returned a position of ':' even if a directory
separator follows. For example, in case of 'x:/', the position of
'/' should be returned not ':'.
mksh_vdirsep() were simplified with mksh_sdirsep().
