POSIX leaves undefined what happens for something like + + awk '{ print ; exit }' if=42 /etc/passwd + + Mawk diagnoses this. Gawk and BWK awk do not. + +2. String comparison with <, <= etc is supposed to take the local collating + sequence into account. Gawk currently doesn't. This is exacerbated + by the fact that the standard routines all want zero-terminated + strings to work on. + +3. For printf %c, when passing a numeric value, it is converted to + a character and printed. I suspect that it should be converted + to a wide-character and then that wide character's multibyte + encoding should be printed. + + Similarly, when given a string, only the first character of the + string should be printed. Right now it only prints the first byte. + +4. Plain `length' is no longer marked obsolescent; the doc needs updating. + +5. The POSIX.STD file needs updating. |
