Ok, I think i have the basics of how to use the two files then. So, using the snippet of code you posted gives the total points for each student, but how do I divide those by 575.25 to get the final percentile score for each student?

I have tried a few things and none seem to work. have tried to do SUM[$1]/575.25... Illegal array reference error
have tried to say x=SUM[s]/575.25 at end, but just got 0 all the way down the list and saying x=SUM[s]/575.25 returned a single name and a 0...

mlib_SignalConv_S16_S16_Sat(3MLIB)			    mediaLib Library Functions				mlib_SignalConv_S16_S16_Sat(3MLIB)

NAME

       mlib_SignalConv_S16_S16_Sat, mlib_SignalConv_S16S_S16S_Sat, mlib_SignalConv_F32_F32, mlib_SignalConv_F32S_F32S - signal convolution

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalConv_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 m, mlib_s32 n);

       mlib_status mlib_SignalConv_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src1, const mlib_s16 *src2, mlib_s32 m, mlib_s32 n);

       mlib_status mlib_SignalConv_F32_F32(mlib_f32 *dst, const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 m, mlib_s32 n);

       mlib_status mlib_SignalConv_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src1, const mlib_f32 *src2, mlib_s32 m, mlib_s32 n);

DESCRIPTION

       Each of these functions performs convolution.

       For monaural signals, the following equation is used:

		m-1
       dst[i] = SUM (src1[j] * src2[i - j])  if m <= n
		j=0

		n-1
       dst[i] = SUM (src2[j] * src1[i - j])  if m > n
		j=0

       where i = 0, 1, ..., (m + n - 2).

       For stereo signals, the following equation is used:

		      m-1
       dst[2*i]     = SUM (src1[2*j] * src2[2*(i - j)])
		      j=0

		      m-1
       dst[2*i + 1] = SUM (src1[2*j + 1] * src2[2*(i - j) + 1])
		      j=0

       if m <= n, or

		      n-1
       dst[2*i]     = SUM (src2[2*j] * src1[2*(i - j)])
		      j=0

		      n-1
       dst[2*i + 1] = SUM (src2[2*j + 1] * src1[2*(i - j) + 1])
		      j=0

       if m > n; where i = 0, 1, ..., (m + n - 2).

PARAMETERS

       Each of the functions takes the following arguments:

       dst	       Destination signal array.

       src1	       First source signal array.

       src2	       Second source signal array.

       m	       Number of samples in the first source signal array.

       n	       Number of samples in the second source signal arrays.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
