Array size in C shell scripting

Hi,

I would like to know how to define the size of the array in c shell scripting.
# 2  
Code:
set x=(40 10 30 20)
echo "${#x}"
4

Compare with bash:
Code:
x=(40 10 30 20)
echo "${#x[@]}"

In bash ${#x} is like ${#x[0]} i.e. the (string-)length of the first element.
# 3  
Is it possible to define the size of the array instead of directly giving the input?

Like x is the array variable and it has the size of 10. So that I could pass the input.
# 4  
The c-shell is very primitive (and buggy).
You cannot declare an array. You have to use the =( ) syntax to extend it.
Clear an array: set x=()
Append an element: set x=($x:q "last")
Prepend an element set x=("first" $x:q)
Change an existing element: set x[1]="new"

Is there any pdf document to learn about c shell scripting? And one more thing is there any way to open the text document using shell scripting?

I cannot recommend the C-shell at all.
My own experience is, it is sufficient for the command line, but it is full of bad surprises if you are going to write longer scripts.
The Internet is full of warnings:
