Thanks for the solution. It works as long as the a and b doesnt equal to 0. It is possible that we may not have to delete any top and bottom records and in that case the value for top and bottom rows will be 0.
grep for a particular pattern and remove 5 lines above the pattern and 6 lines below the pattern

Hi,
I have a file, which is having a pattern "SEARCH" somewhere towards end of the file,

glortho
GLORTHO(3G)GLORTHO(3G)NAME
glOrtho - multiply the current matrix with an orthographic matrix
C SPECIFICATION
void glOrtho( GLdouble left,
GLdouble right,
GLdouble bottom,
GLdouble top,
GLdouble zNear,
GLdouble zFar )
PARAMETERS
left, right Specify the coordinates for the left and right vertical clipping planes.
bottom, top Specify the coordinates for the bottom and top horizontal clipping planes.
zNear, zFar Specify the distances to the nearer and farther depth clipping planes. These values are negative if the plane is to be behind
the viewer.
DESCRIPTION
glOrtho describes a transformation that produces a parallel projection. The current matrix (see glMatrixMode) is multiplied by this matrix
and the result replaces the current matrix, as if glMultMatrix were called with the following matrix as its argument:
2
------------ 0 0 tx
right - left
2
0 ------------ 0 ty
top - bottom
-2
0 0 ------------ tz
zFar-zNear
0 0 0 1
where
tx = - (right + left) / (right - left)
ty = - (top + bottom) / (top - bottom)
tz = - (zFar + zNear) / (zFar - zNear)
Typically, the matrix mode is GL_PROJECTION, and (left, bottom, -zNear) and (right, top, -zNear) specify the points on the near clipping
plane that are mapped to the lower left and upper right corners of the window, respectively, assuming that the eye is located at (0, 0, 0).
-zFar specifies the location of the far clipping plane. Both zNear and zFar can be either positive or negative.
Use glPushMatrix and glPopMatrix to save and restore the current matrix stack.
ERRORS
GL_INVALID_OPERATION is generated if glOrtho is executed between the execution of glBegin and the corresponding execution of glEnd.
