Interpolation using awk

Hi all,
Consider I have a text file containing:
Code:
1003   60
1005   80
1100   110

Based on that file I need to create another file which is containing value from 1001 till 1100 which is a linear interpolation between two point (for 1004; 1006;1007 until 1109) and extrapolation based on 2 point (for 1001 and 1002; based on equation from 1003 and 1005 value)

I wonder if it could be done by using AWK script. Or if there is another solution it would be wonderful.

Thank you

PPIx::Regexp::Token::Interpolation(3)			User Contributed Perl Documentation		     PPIx::Regexp::Token::Interpolation(3)

NAME
PPIx::Regexp::Token::Interpolation - Represent an interpolation in the PPIx::Regexp package. SYNOPSIS
use PPIx::Regexp::Dumper; PPIx::Regexp::Dumper->new('qr{$foo}smx')->print(); INHERITANCE
"PPIx::Regexp::Token::Interpolation" is a PPIx::Regexp::Token::Code. "PPIx::Regexp::Token::Interpolation" has no descendants. DESCRIPTION
This class represents a variable interpolation into a regular expression. In the "SYNOPSIS" the $foo would be represented by an object of this class. METHODS
This class provides no public methods beyond those provided by its superclass. ppi This convenience method returns the PPI::Document representing the content. This document should be considered read only. Note that the content of the returned PPI::Document may not be the same as the content of the original "PPIx::Regexp::Token::Interpolation". This can happen because interpolated variable names may be enclosed in curly brackets, but this does not happen in normal code. For example, in "/${foo}bar/", the content of the "PPIx::Regexp::Token::Interpolation" object will be '${foo}', but the content of the "PPI::Document" will be '$foo'. SUPPORT
