Ha, ha! Another classic example of changing requirements. Ok, here's some light:
if($. == 1) {print; next} ==> This part of the code checks if line in consideration is line #1 and if so prints the line as-is and proceeds to next line. This is because, from your initial sample in post #1, first line is the header line (obs freq (1/n) cumfreq).
Here's one to suit your requirement from post #5:

I have a question how to decrypt text uses letter frequency analysis. I have code which count the letters, but what i need to do after that. Can anybody help me to write a code. VERY NEEDED! My code now:

Dear all,
i need your help on this. There is a text file, i need to count word frequency for each word with frequency >40 in each line of file and output it into another file with columns like this:

mlib_SignalMelCepstral_S16(3MLIB) mediaLib Library Functions mlib_SignalMelCepstral_S16(3MLIB)NAME
mlib_SignalMelCepstral_S16 - perform cepstral analysis in mel frequency scale
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalMelCepstral_S16(mlib_s16 *cepst,
mlib_s32 cscale, const mlib_s16 *signal, void *state);
DESCRIPTION
The mlib_SignalMelCepstral_S16() function performs cepstral analysis in mel frequency scale. The user supplied scaling factor will be used
and the output will be saturated if necessary.
The first two steps of mel scale cepstral analysis is the same as in general cepstral anaysis. After the logarithm of the spectrum magni-
tude is obtained, it is converted into mel frequency scale before the inverse Fourier transform.
+-----------+ +-----------+
| Linear | | Inverse |
... ------>| to |------->| Fourier |----->
X'(k) | Mel Scale | X''(m) | Transform | c(n)
+-----------+ +-----------+
where X'(k) is defined in linear frequency scale and X''(m) is defined in mel frequency scale.
The mel frequency scale is defined as following.
freq_mel = melmul * LOG10(1 + freq_linear / meldiv)
where freq_mel is the frequency in mel scale, freq_linear is the frequency in linear scale, melmul is the multiplying factor, muldiv is the
dividing factor.
Optionally, a bank of band pass filters in linear frequency scale can be used below the bank of band pass filters in mel frequency scale,
as shown below in linear frequency scale.
0 f1 f2 f3 fp fp+1 fp+2 fp+3 fp+q
|---|---|---| ... |---|----|-----| ... | ... -> freq
where fp = melbgn, fp+q = melend, p = nlinear, q = nmel; the filters number 1 to p are defined in linear frequency scale which have equal
bandwidth in linear frequency scale; the filters number p+1 to p+q are defined in mel frequency scale which have equal bandwidth in mel
frequency scale and increasing bandwidth in linear frequency scale.

PARAMETERS
The function takes the following arguments:
cepst The cepstral coefficients.
cscale The scaling factor of cepstral coefficients, where actual_data = output_data * 2**(-scaling_factor).
signal The input signal vector, the signal samples are in Q15 format.
state Pointer to the internal state structure.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
