Description:
        [In bash scripts I have noticed that if I have a variables inside 'for while' loops that after the 'done' statement the loop variables are not accessable. Ie echo $var has no value where it just did inside the loop. Below is and example of where I found this behavior. Please look at the fileline variable which is affected by the above stated condition. 

#!/bin/bash
#BUILD ARRAY
libname=$1
docnumber=$2
arrayfileline=1
cat ${libname}.log | tr -d "\0" > ${libname}2.log
rm ${libname}.log
cat ${libname}2.log | while read LINE
do
 export fileline[$arrayfileline]=$LINE
 ((arrayfileline=arrayfileline+1))
 linecount=`echo ${#fileline[*]}`
 echo $linecount > /tmp/linecount
done
################
getarrayline=1
linecount=`cat /tmp/linecount`
linestat=go
while [ $linestat == go ]
do
 echo "ARRAY LINE ${fileline[$getarrayline]}"
 echo ${fileline[$getarrayline]} | grep $docnumber > /dev/null
 if [ $? -eq 0 ] #FOUND DOC IN NDX LOG
 then
  ((getnextline=getarrayline+1))
  echo "${fileline[$getarrayline]} ${fileline[$getnextline]}"
 fi
 ((getarrayline=getarrayline+1))
 if [ $linecount == $getarrayline ]
 then
  linestat=nogo
 fi
Done]

Repeat-By:
        [#!/bin/bash
#BUILD ARRAY
libname=$1
docnumber=$2
arrayfileline=1
cat ${libname}.log | tr -d "\0" > ${libname}2.log
rm ${libname}.log
cat ${libname}2.log | while read LINE
do
 export fileline[$arrayfileline]=$LINE
 ((arrayfileline=arrayfileline+1))
 linecount=`echo ${#fileline[*]}`
 echo $linecount > /tmp/linecount
done
################
getarrayline=1
linecount=`cat /tmp/linecount`
linestat=go
while [ $linestat == go ]
do
 echo "ARRAY LINE ${fileline[$getarrayline]}"
 echo ${fileline[$getarrayline]} | grep $docnumber > /dev/null
 if [ $? -eq 0 ] #FOUND DOC IN NDX LOG
 then
  ((getnextline=getarrayline+1))
  echo "${fileline[$getarrayline]} ${fileline[$getnextline]}"
 fi
 ((getarrayline=getarrayline+1))
 if [ $linecount == $getarrayline ]
 then
  linestat=nogo
 fi
Done.]
