Its a two part problem

So this .sh is the array that works fine (I think ) for what I need it to do.

Code:
#!/bin/bash 

IFS=$'\n' 
fortune_lines=($(fortune | fold -w 30))

for var in "${fortune_lines[@]}"
do
  echo "${var}"
done

but I want to append that array into a loop that would look like this (its not working - and I really have no idea what the next step should be to make this work ) but here is a rough idea

Code:
#!/bin/bash 

IFS=$'\n' 
fortune_lines=($(fortune | fold -w 30))
Screen_Session=$(mainscreen)
Screen_OneLiner=$(screen -p 0 -S ${Screen_Session} -X stuff "`printf "say ${fortune_lines[@]}\r"`")



for var in "${Screen_OneLiner[@]}"
do
  echo "${var}"
done



Then when executed I get a black window, in the bottom bar it says
"cannot exec stuff"

Then the terminal that I am
Code:
./

the .sh from prints and drops back to the prompt
Code:
 line 5: mainscreen: command not found
[screen is terminating]

Other info
I am starting my screen session (Screen version 4.00.03 (FAU) 23-Oct-06
) using
Code:
screen -S mainscreen

and the bash version I am using is
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin12)

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
