.func isalnmkana

int isalnmkana( int c );
.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function tests if the argument
.arg c
is a single-byte alphanumeric character ("a" to "z", "A" to "Z", or
"0" to "9") or single-byte Katakana non-punctuation character.
These are any characters for which the following expression is true:
.millust begin
isalnum(c) || iskmoji(c)
.millust end
.desc end
.return begin
The &func function returns zero if the argument is not a single-byte
alphanumeric character or single-byte Katakana non-punctuation
character;
otherwise, a non-zero value is returned.
