Why this statement does not print anything in an if-statement that includes 'q()'?
...e the second 'length(args)' to
'print(length(args))', the script will print the length of 'args'. Can
somebody let me know what is the difference between the 'print(x)'
statement and the 'x' statement where 'x' is a variable?
Regards,
