help with doing calculations on data

Dear All, I have a long list like this: 337 375 364 389 443 578 1001 20100 . . . . etc I would like to substract each value from the first entry which in this case is 337 and report it in a separate column. So the expected output looks like 337 0

gcomp

GCOMP(1)						      General Commands Manual							  GCOMP(1)

NAME

       gcomp - do computations on a graph file.

SYNOPSIS

       gcomp [ -amilh ][ +variable value ..  ][ file ..  ]

DESCRIPTION

       Gcomp reads each graph file in sequence and computes the specified calculations.  The type options are as follows:

       -n	 Print the name of each curve.

       -a	 Print average and standard deviation of each curve.

       -m	 Print minimum and maximum for each curve.

       -i	 Print Romberg's approximation to the integral of each curve.

       -l	 Print the slope, intercept, and correlation coefficient using the least squares method of linear regression.

       -h	 Do not print a header in the output.

       The  calculations  will	be  displayed as columns in the order they are specified on the command line.  If no files are given, the standard
       input is read.

       Variables can be set explicitly with +variable value options.  The only truely useful variables for this program are xmin and  xmax.   They
       determine boundaries for the calculations.

EXAMPLE

       To compute the approximate integral of sin(x)/log(x) from 2 to 4:
	    gcomp -i
	    A(x)=sin(x)/log(x);
	    Anpoints=100;
	    xmin=2;
	    xmax=4;
	    ^D
