Resolving Var to its contents

Hello everyone....
I am trying to dinamically create variable names and do resolution of this vars contents.
After that is done I want to use (via a function call) the var and its contents by referring to it via the variable name.
I am having a hard time achieving this .... can you help ?

Example:

Code:

#! /bin/ksh

_func2(){
emt=test1_$1
emc=test2_$1
   echo $emt
   echo $emc

emt=$emt"_EM"
emc=$emc"_EM"
   echo $emt
   echo $emc
}

Datenow=`date +%Y%m%d%H%M`
test1_x1=/dir1/test/FileOneOne_$Datenow
test1_x2=/dir1/test/FileOneTwo_$Datenow

test2_x1=/dir1/test/FileTwoOne_$Datenow
test2_x2=/dir1/test/FileTwoTwo_$Datenow

test1_x1_EM=/dir1/test/OneOne_$Datenow
test1_x2_EM=/dir1/test/OneTwo_$Datenow

test2_x1_EM=/dir1/test/TwoOne_$Datenow
test2_x2_EM=/dir1/test/TwoTwo_$Datenow

_func2  x1
_func2  x2

When I run this I get the following output, how can I get the variable to resolve to its content?

Code:

test1_x1
test2_x1
test1_x1_EM
test2_x1_EM
test1_x2
test2_x2
test1_x2_EM
test2_x2_EM

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of

       file names common to both directories have the same contents.

OPTIONS

       The following options are supported:

       -d	Compares  the  contents  of files with the same name in both directories and output a list telling what must be changed in the two
		files to bring them into agreement. The list format is described in diff(1).

       -s	Suppresses messages about identical files.

       -w n	Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1	A path name of a directory to be compared.
       dir2

USAGE

       See largefile(5) for the description of the behavior of dircmp when encountering files greater than or equal to 2 Gbyte ( 2**31bytes).

ENVIRONMENT VARIABLES

       0	Successful completion.

       >0	An error occurred. (Differences in directory contents are not considered errors.)
