Multiple line user input

[jointhelabel]

I'm trying to write a program that accepts user input to find a particular file and perform a particular action. I can't seem to make it so that the user in Windows CMD can type multiple lines, like in a text file, rather than just one line at a time. I'd like to use readLine() or some equivalent after the user enters the information to read and disperse the various components, but i don't know if that's possible. This is the format of user input i need from the command prompt.

GET \userinfo\scenario4.txt
(blank line)
additional optional data(could be any length)

the blank line is an actual blank line. any help would be much appreciated.

I'd like to use readLine()

By definition readLine reads a line, not more than one line.
When reading from console input, how will you detect the end of the user's input? If optional data follows a blank line, then the user will have to signal end of input for the program to recognize it.
On some OSs there is a control key + letter combo to signal EOF.
I think it's Ctrl+C on Windows but am not sure.

To read more than one line, put the readLine() in a loop and continue reading until EOF is signalled.

I don't think in Windows command prompt you can enter multiple lines. I think Ctrl+C is the terminate command of e process, cannot use for EOF notification.

Since readLine() read a line-by-line, you can read all information through a single line by use of a special character separation, may be a comma or any other characters. Then you can process it in your application before read the file and so on. Just a tip.

Try CTRL+Z and Enter for EOF.
Remember EOF will mean that you can NOT read any more from the console.
