Shell Programming and Scripting

I am a FORTRAN guy and not a UNIX expert by any means so sorry if this sounds dumb, but all I want to do is have a UNIX script which reads data from a file (say 1000 lines worth, each row is a file name) and store it in an array to perform an operation on later. As maddeningly simple as this sounds I cannot do it!
I do not need to parse the data or manipulate it in any way.

Could someone please help?

Thanks.

Older versions of ksh limit the number of elements in an array to 1024. (0 to 1023).

Code:

#! /bin/ksh

let i=1
while read file
do
   filenames[$i]=$file
   let i=$i+1 
   print $i
done < myfile

let j=1

while [ $j -le $i ]
do
    echo "${filenames[j]}"
    let j=$j+1
done

#the code is
x=0
while read -r var
do
filename[ $x ]=$var
x=`expr $x + 1`
done < file
y=0
while [ $y -le $x ]
do
echo $filename[ $y ]
y= `expr $y + 1`
done
