calling a aliased variable

Issue:

i have variable A which is an alias for variable B which is equal to "THIS IS A TEST"

when every i echo variable A i only get the alias name for variable B, NOT the contents of variable B.



Code:
HOSTNAME# echo $TESTIT
+ echo THIS IS A TEST
THIS IS A TEST

HOSTNAME# ls -l
total 16
-rw-r--r--   1 user group        6 Jul 15 13:58 TEST.IT


HOSTNAME# for i in `ls`; do
DOH=`echo $i|awk -F. '{ print "$"$1$2 }'`
echo $DOH
done
$TESTIT


HOSTNAME#

NAME
incr - Increment the value of a variable SYNOPSIS
incr varName ?increment? _________________________________________________________________ DESCRIPTION
Increments the value stored in the variable whose name is varName. The value of the variable must be an integer. If increment is supplied then its value (which must be an integer) is added to the value of variable varName; otherwise 1 is added to varName. The new value is stored as a decimal string in variable varName and also returned as result. EXAMPLES
Add one to the contents of the variable x: incr x Add 42 to the contents of the variable x: incr x 42 Add the contents of the variable y to the contents of the variable x: incr x $y Add nothing at all to the variable x (often useful for checking whether an argument to a procedure is actually numeric and generating an error if it is not): incr x 0 SEE ALSO
