Ktune - Red Hat ENTERPRISE LINUX 5.5 - TECHNICAL NOTES Manual

called within a ksh function (defined with the "function" syntax). With this update, referencing the $!
special variable works as expected and the correct process ID of the last background job or function is
returned, even when it is referenced from within a ksh script function.
* when a ksh script included multibyte characters, the ksh script parser sometimes failed to parse the
script and printed a syntax error message. This updated package corrects this error: the ksh script
parser now correctly handles multibyte characters and no error is returned when they are found.

* when the built-in ksh typeset function was used with the array variable, it was affecting the size of the
array by appending one empty value. This is now corrected and typeset does not unintentionally affect
size of arrays. (BZ#538857
* some upstream behavioural changes of ksh were not sufficiently documented, specifically
parenthesis which was supported in ksh-93r or older. ksh Now ships Release and ChangeLog
documents wherein important changes are documented.
* when evaluating a non-number variable that contains a point in a numeric comparison, ksh crashed
with a segmentation fault. With this update, ksh checks whether the point has numerical or parent
separator meaning, and produces only an error message when appropriate.
* when the array variable was declared using the built-in 'set', but not defined, this declaration did
not take effect. The built-in 'set' included in the updated ksh declares array variables correctly.

All users of ksh are advised to upgrade to this updated package, which resolves these issues.
