[ Solved ] Sort String using awk

Excellent!!
Thanks for your help. I don't have GNU awk so all other solutions works good for me.

Last suggestion given by Chubler_XL does not give right output but rest all works good.
Thanks for your support.

Hi,

Sorry to come back again on same issue.I am stuck again with solution
I am trying to use solution provided by shamrock
How do I put that part in function so that whatever string I pass, it will sort and give me output in variable for further usage like comparison as below
Code:
snamelist="AAAB,ABCddf,LMNS,PQR:VALUE1 AAB,ABSSf,LMNS,DFD:VALUE2 LMNS,ABCddf,PQR,AAAB:VALUE3"
for sname in $snamelist
do
    BASELINE="AAAB,ABCddf,LMNS,PQR"
    echo  "$sname" | awk -v baseline="$BASELINE" 'BEGIN { FS=":" }
    { pref=$1 ; if (pref == baseline) { svcstatus = "OK" } else { svcstatus = "NOT-OK" }  ;
    printf "%-35s %-35s %-35s %-10s\n", sname, pref, baseline, svcstatus}'
done

In my actual program, pref and baseline will not be shell variable but variable in awk itself derived based on line of input. So before comparing (pref == baseline), I want to sort both so that compare can work. something like below where sortme will be function defined inline using code provided by shamrock.
looking something as below
Code:
snamelist="AAAB,ABCddf,LMNS,PQR:VALUE1 AAB,ABSSf,LMNS,DFD:VALUE2 LMNS,ABCddf,PQR,AAAB:VALUE3"
for sname in $snamelist
do
    BASELINE="AAAB,ABCddf,LMNS,PQR"
    echo  "$sname" | awk -v baseline="$BASELINE" 'BEGIN { FS=":" }
{<DEFINE SORTME FUNCTION HERE>}
    { pref=$1 ; if (sortme(pref) == sortme(baseline)) { svcstatus = "OK" } else { svcstatus = "NOT-OK" }  ;
    printf "%-35s %-35s %-35s %-10s\n", sname, pref, baseline, svcstatus}'
done

Appreciate your help.

PROP_SEND_SYCALL(3)					   BSD Library Functions Manual 				       PROP_SEND_SYCALL(3)

NAME
prop_array_send_syscall, prop_array_recv_syscall, prop_dictionary_send_syscall, prop_dictionary_recv_syscall -- send and receive property lists to and from the kernel using syscalls SYNOPSIS
#include <prop/proplib.h> int prop_array_send_syscall(prop_array_t array, struct plistref *prefp); int prop_array_recv_syscall(const struct plistref *prefp, prop_array_t *arrayp); int prop_dictionary_send_syscall(prop_dictionary_t dict, struct plistref *prefp); int prop_dictionary_recv_syscall(const struct plistref *prefp, prop_dictionary_t *dictp); DESCRIPTION
The prop_array_send_syscall, prop_array_recv_syscall, prop_dictionary_send_syscall, and prop_dictionary_recv_syscall functions implement the user space side of a protocol for sending property lists to and from the kernel using syscall(2). RETURN VALUES
If successful, functions return zero. Otherwise, an error number is returned to indicate the error. EXAMPLES
The following (simplified) example demonstrates using prop_dictionary_send_syscall() and prop_dictionary_recv_syscall() in an application: void foo_setprops(prop_dictionary_t dict) { struct pref pref; (void) prop_dictionary_send_syscall(dict, &pref); (void) my_syscall_set(&pref); } prop_dictionary_t foo_getprops(void) { prop_dictionary_t dict; struct pref pref; (void) my_syscall_get(&pref); if (prop_dictionary_recv_syscall(&pref, &dict) != 0) return (NULL); return (dict); } ERRORS
prop_array_send_syscall() and prop_dictionary_send_syscall() will fail if: [ENOMEM] Cannot allocate memory [ENOTSUP] Not supported prop_array_recv_syscall() and prop_dictionary_recv_syscall() will fail if: [EIO] Input/output error [ENOTSUP] Not supported SEE ALSO
