I have a ksh93 script that I'm migrating from AIX 6.1 to AIX 7.1It's failing on 7.1 but works fine on 6.1.  Here's a snippet of the important parts.integer f_count=0   . . .    . . .    . . . if [[ ($f_count*$sleep_interval%$alarm_interval -eq 0 ) && $f_count > 0 ]]       thenWhen it hits the if I getline 191: *10%300: arithmetic syntax errorI decided to simplify it by typing this at the command prompt.AIX 7.1> integer x=1          AIX 7.1> [[ $x*10%300 -eq 0 ]]AIX 7.1> print $?1AIX 7.1> integer x=0          AIX 7.1> [[ $x*10%300 -eq 0 ]]-ksh93: *10%300: arithmetic syntax errorAIX 6.1> integer x=1          AIX 6.1> [[ $x*10%300 -eq 0 ]] AIX 6.1>  print $?                                                                                        1AIX 6.1>  integer x=0                                                           AIX 6.1>  [[ $x*10%300 -eq 0 ]] AIX 6.1>  print $?                                                                                        0To show it's ksh93 on AIX 6.1 I did this.asdlkfjasd-ksh93: asdlkfjasd: not found.If I move the 0 value so it's not first, it works as expected.AIX 7.1> integer x=1            AIX 7.1> [[ 10*$x%300 -eq 0 ]]  AIX 7.1> print $?             1AIX 7.1> integer x=0           AIX 7.1> [[ 10*$x%300 -eq 0 ]]  AIX 7.1> print $?             0This will fix my issue as I know the 2nd and 3rd variables in my original equation will never be 0.Is this showing an AIX 7.1 bug?
[[ 0*10%300 ]] works on AIX 6.1 but not on AIX 7.1 (ksh)
