HPUX is probably using ksh88 where the scoping of variables was undefined. ksh93 has static scoping specified and this is the expected behaviour. Please have a look at the official KornShell FAQ, Question 28 at http://www.kornshell.com/doc/faq.html |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.1) Gecko/20040707 Description of problem: local variables are not passed to subordinated functions (see example below) In posix shell, pdksh and on HPUX ksh the output of the sample script is string1 string2 whereas ksh-20040229 outputs string1 string1 EXAMPLE =============== function A { print $Var } function B { Var=string1 A typeset Var Var=string2 A } # MAIN B # invoke test function Version-Release number of selected component (if applicable): ksh-20040229-12.i386.rpm How reproducible: Always Steps to Reproduce: 1. Run scriptlet in ksh 2. 3. Actual Results: string1 string1 Expected Results: string1 string2 Additional info: Of course I can work around this by passing the parameter(s) to the function which would be good style anyway. But because other ksh versions behave differently every legacy script has to be reviewed to make sure all results are correct.
