How do I read a file, row by row and not strip off white spaces as 'read' does. I am using the pre 88 version of ksh.

This is my current read of a file which I test conditions and edit records. None of my trailing spaces are read from this line.
 cat $AIXX_MVR_RESULT_FILE | while IFS="\n" read resLine

Below is a line, which reads without trimming the trailing white spaces.
     resLine=$(echo "$line" | cut -c0-$editOffset)

How do I incorporate the above line in a while loop as the cat is doing above.
The snippet below is the bigger example.

###########################################################
# Replace the result file posn/bsn with the previouly
# captured posn/bsn for AIXX Result
#########################################################
            cat $AIXX_MVR_RESULT_FILE | while read resLine
              do
               aixxRecType=$(echo $resLine | cut -c0-2)
               if [ $aixxRecType == "04" ]; then
                 print "04 Record type found:"$aixxRecType
                 # Substitute posn/bsn
                 typeset substitutionLength=29
           
                 returnedSubString=" "
           print "RESLINE befory function:"$resLine
                 SubStringFunc1 $resLine $QUOTEBACK 5 $substitutionLength
                fi
            resLine=$(printf "%-80s" $resLine)
            print $resLine >>$RESULT_HOME/$UNQ_AIDS_RESULT.aidsMvr
            resLine=" "
              done

Try this:

IFS="\n"

cat "$1" | while read line; do
    echo "Line = $line"
done
