The script needs urgent revision because it has some serious problems which may not produce syntax errors or error messages (?) but which cause alarming process anomalies due to command truncation in AIX. Have you counted the number of input files and compared with the number of output files?
I would suggest avoiding any unlimited xargs in AIX and executing comands one-by-one. Credit: Scrutinizer picked up on this.

Code:
stmt_cnt=$(ls -1 ${1}/${2}|wc -l) 
   if [ ${stmt_cnt} -ne 0 -a ${stmt_cnt} -lt 501 ]; then
     out_str="${out_str}\n$(date +"%Y%m%d%H%M%S"): Moving ${stmt_cnt} \"${2}\" statements from ${1} to ${3}\n"
     find ${1} -type f -name "${2}"|while read filename
     do
                mv "${filename}" "${3}"
     done
  fi

I have no idea what the sort is for and IMHO the ksh command line with the foobar is a botch to lose a surplus parameter when the command line is too long.
You clearly did not write this script but it is hard to justify that this script works despite the absence of reported syntax or other error messages.

Sorry to be so abrupt but that ksh line is a real problem.

Agreed, foobar is confusing here but works so syntax is not an issue
Are you really sure? I'm not so sure.

$1 = starting directory
$2 = pattern
$3 = destination
Let's assume that $3 is a pre-existing writeable directory. We don't know anything about $2, but that could be the subject of the next post.

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
