Thanks. That takes care of some of it. The other problem is the input order. The getops is fantastic for taking in one argument, but only if they are after a switch.
For this, I would suggest u to develop your script in such a way that it accepts options first and than two numbers at last.
For example:
So, build a logic which accepts two numbers followed by all valid options as command line arguments.

FONT(6) Games Manual FONT(6)NAME
font, subfont - external format for fonts and subfonts
SYNOPSIS
#include <libg.h>
DESCRIPTION
Fonts and subfonts are described in cachechars(2).
External fonts are described by a plain text file that can be read using rdfontfile. The format of the file is a header followed by any
number of subfont range specifications. The header contains two numbers: the height and the ascent, both in pixels. The height is the
inter-line spacing and the ascent is the distance from the top of the line to the baseline. These numbers are chosen to display consis-
tently all the subfonts of the font. A subfont range specification contains two or three numbers and a file name. The numbers are the
inclusive range of characters covered by the subfont, with an optional starting position within the subfont, and the file name names an
external file suitable for rdsubfontfile. The minimum number of a covered range is mapped to the specified starting position (default
zero) of the corresponding subfont. If the subfont file name does not begin with a slash, it is taken relative to the directory containing
the font file. Each field must be followed by some white space. Each numeric field may be C-format decimal, octal, or hexadecimal.
External subfonts are represented in a more rigid format that can be read and written using rdsubfontfile and wrsubfontfile (see subfal-
loc(2)). The format for subfont files is: a bitmap containing character images, followed by a subfont header, followed by character infor-
mation. The bitmap has the format for external bitmap files described in bitmap(6). The subfont header has 3 decimal strings: n, height,
and ascent. Each number is right-justified and blank padded in 11 characters, followed by a blank. The character info consists of n+1
6-byte entries, each giving the Fontchar x (2 bytes, low order byte first), top, bottom, left, and width. The x field of the last Fontchar
is used to calculate the bitmap width of the previous character; the other fields in the last Fontchar are irrelevant.
Note that the convention of using the character with value zero (NUL) to represent characters of zero width (see bitblt(2)) means that
fonts should have, as their zeroth character, one with non-zero width.
