Just a couple more quick questions.

Code:
set -- $(ls -ld $file)

What is the use of the double --?

I have read up and it states that it doesnt allow change of any of the flag, useful in setting $1 to "-".

Im not 100% sure what it means, I have tested with one - and two and found that you could not change the file name whilst using one as an error occured.

SYNOPSIS
float fann_train_epoch (resource $ann, resource $data) DESCRIPTION
Train one epoch with the training data stored in data. One epoch is where all of the training data is considered exactly once. This function returns the MSE error as it is calculated either before or during the actual training. This is not the actual MSE after the training epoch, but since calculating this will require to go through the entire training set once more. It is more than adequate to use this value during training. The training algorithm used by this function is chosen by fann_set_training_algorithm(3) function. PARAMETERS
o $ann -Neural network resource. o $data -Neural network training data resource. RETURN VALUES
The MSE, or FALSE on error. SEE ALSO
