If the line you want to change is the 4th line in each file:

Code:
$ ls
queue_11.txt  queue_12.txt	 queue_13.txt

Code:
$ ls Que*.txt |
> while read FILE
> do
> sed '4s/F/FQ/' ${FILE} > ${FILE}.new
> done

Code:
$ ls
queue_11.txt.new	queue_12.txt.new  queue_13.txt.new
queue_11.txt  queue_12.txt	queue_13.txt

Code:
$ cat Queue_11.txt.new 
reload sec=F
Code=7
reload sec=F
reload sec=FQ
No-load=F1
Reset
NULL
A-cap=LA
reload sec=F

$ cat Queue_12.txt.new
reload sec=F
Code=7
reload sec=F
reload sec=FQ
No-load=F1
Reset
NULL
A-cap=LA
reload sec=F

$ cat Queue_13.txt.new
reload sec=F
Code=7
reload sec=F
reload sec=FQ
No-load=F1
Reset
NULL
A-cap=LA

glfrontface

GLFRONTFACE(3G) 														   GLFRONTFACE(3G)

NAME

       glFrontFace - define front- and back-facing polygons

C SPECIFICATION

       void glFrontFace( GLenum mode )

PARAMETERS

       mode  Specifies the orientation of front-facing polygons.  GL_CW and GL_CCW are accepted.  The initial value is GL_CCW.

DESCRIPTION

       In  a  scene composed entirely of opaque closed surfaces, back-facing polygons are never visible.  Eliminating these invisible polygons has
       the obvious benefit of speeding up the rendering of the image.  To enable and disable elimination of back-facing  polygons,  call  glEnable
       and glDisable with argument GL_CULL_FACE.

       The  projection	of  a  polygon	to window coordinates is said to have clockwise winding if an imaginary object following the path from its
       first vertex, its second vertex, and so on, to its last vertex, and finally back to its first vertex, moves in a clockwise direction  about
       the interior of the polygon.  The polygon's winding is said to be counterclockwise if the imaginary object following the same path moves in
       a counterclockwise direction about the interior of the polygon.	glFrontFace specifies whether polygons with clockwise  winding	in  window
       coordinates, or counterclockwise winding in window coordinates, are taken to be front-facing.  Passing GL_CCW to mode selects counterclock-
       wise polygons as front-facing; GL_CW selects clockwise polygons as front-facing.  By default, counterclockwise polygons	are  taken  to	be
       front-facing.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_OPERATION is generated if glFrontFace is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_FRONT_FACE
