How to capture system() function output in variable

How to capture system() function output in awk variable and the print that awk variable.....

A system() function is a shell.
If the order doesn't matter,
it is usually better to first start with a shell, then invoke awk from there and pass arguments. Example:
x=$(whatever command)
awk -v x="$x" 'awk code can use the x variable'

All you can capture into a variable is the exit code of the command executed by the system function, like A=system("ls"). The output of ls is printed to stdout immediately.

You can store the output of an external command invoked from inside awk,
but you should not use the system function for that:
zsh-5.0.2[user]% awk 'BEGIN { "date" | getline dt; print "Got", dt }'
