/usr/sbin [18]: 0403-057 Synatx error at line 83 is > not expected.

Question:

ENV:
   AIX 4.1.3
   RISC C20-7009
   TAPE  7206-005 4mm 4gb
   sysback 4.1.4.3

Problem:
  The customer runs this command:

  mkjfsback -xf /dev/rmt0 /u /u1 /u2 /u3

  The command fails with this error message:

  /usr/sbin [18]: 0403-057 Synatx error at line 83 is > not expected

Action Taken:
1.  export SBDEBUG=1

2. mkjfsback -xf /dev/rmt0 /u /u1 /u2 /u3   
     It fails at this command within the mkjfsback script
     runcommand2 /usr/sbin/sbrunshell isdir /dev/rmt0

3.  I had the customer run the command from the command line
      /usr/sbin/sbrunshell isdir /dev/rmt0
     It failed with the same exact message

4.  cd /usr/sbin
    vi sbrunshell
    Went to line 83

  ((pid = pid + 0)) 2>/dev/null

5.  I had the customer run that on the command line
      pid=5
      ((pid = pid + 0)) 2>/dev/null

      It failed with the same error message above
      It appears to be a defect in the ksh shell
      
I found this APAR:

PTF       APAR      Level    Fileset         Description
--------------------------------------------------------------
U439459  IX53225   4.1.3.4  bos.rte.shell   (( 5 )) > FILE IN 
                                            KSH FAILS

6.  I had the customer use the fixdist from the web and 
    download the fix and install it which corrected the 
    problem

Action Plan: 
  Closing with customer approval
