#!/bin/bash

NAME="John" "Mary" "Fred"
SURNAME="Doe" "Poppins" "Flintstone"

for i in $@


You should quote $@.

Code:
do

NAME[${#NAME[@]}]=$i
SURNAME[${#SURNAME[@]}]=$i
done

for ((i=0; i < ${#NAME[@]}; i++))


That is non-standard syntax. To loop through all elements of an array:

Code:
for i in "${NAME[@]}"

Quote:
Code:
do

typeset NAME[$i]="${SURNAME[$i]}"


What's the point of typeset? It is non-standard, and doesn't do anything here.
Quote:
Code:
done

echo "$John"
echo "$Mary"
echo "$Fred"


Use eval:

Code:
eval "${NAME[$i]}=\${SURNAME[$i]}"

MESSAGES(3)						  libbash messages Library Manual					       MESSAGES(3)

NAME

     messages -- libbash library that implements a set of functions to print standard status messages

SYNOPSIS

     printOK	 [indent]
     printFAIL	 [indent]
     printNA	 [indent]
     printATTN	 [indent]
     printWAIT	 [indent]

DESCRIPTION

   General
     messages is a collection of functions to print standard status messages - those [ OK ] and [FAIL] messages you see during Linux boot process.

     The function list:
	   printOK	    Prints a standard [ OK ] message (green)
	   printFAIL	    Prints a standard [FAIL] message (red)
	   printNA	    Prints a standard [ N/A] message (yellow)
	   printATTN	    Prints a standard [ATTN] message (yellow)
	   printWAIT	    Prints a standard [WAIT] message (yellow)

     Detailed interface description follows.

   indent
     Column to move to before printing.

     Default indent is calculated as TTY_WIDTH-10. If current tty width can not be determined (for example, in case of serial console), it
     defaults to 80, so default indent is 80-10=10

FUNCTIONS DESCRIPTIONS

   printOK [indent]
     Prints a standard [ OK ] message (green)

   printFAIL [indent]
     Prints a standard [FAIL] message (red)

   printNA [indent]
     Prints a standard [ N/A] message (yellow)

   printATTN [indent]
     Prints a standard [ATTN] message (yellow)

   printWAIT [indent]
     Prints a standard [WAIT] message (yellow)

EXAMPLES

     Run a program named MyProg, and report it's success or failure:

	      echo -n 'Running MyProg...'
	      printWAIT
	      if MyProg ; then
		      printOK
	      else
		      printFAIL
	      fi
