I have the following script:
    /buffer 80 string def
    /inputFile INPUT (r) file def
    {
        inputFile buffer readline {
            =
        }{
            pop
            inputFile closefile
            exit
        } ifelse
    } loop

This displays the file. But instead of displaying I would like to put
the lines into an array.

Just keeping the values on the stack Like:
    /buffer 80 string def
    /inputFile INPUT (r) file def
    {
        inputFile buffer readline {
            % Keep it on the stack
        }{
            pop
            inputFile closefile
            exit
        } ifelse
    } loop
    stack

does not work, because the lower values are overwritten.

The first script gives:
    They are not only idle who do nothing,
    but they are idle also
    who might be better employed.

    Socrates

While the second gives:
    Socrates

    Socratest be better employed.
    Socratest be better em
    Socratest be better employed. nothing,

How would I get the lines correctly into an array?
