Compiling the Program

Use the

pc

command to compile the program and store it in the executable file

copy

. Here is the command format:

hostname% pc -o copy copy.p

Running the Program

Because the standard files

input

and

output

default to the terminal, the

program simply echoes each line you type. The program terminates when you
type the end-of-file (Control-d) character at the beginning of a line. Try it:

Redirecting I/O

To write the output to a file instead of to the terminal, use the redirection
operator,

>

, followed by a file name. For instance, to write to a file called

data

, enter the following:

hostname% copy

hello, are you listening?

hello, are you listening?

goodbye, I must go now.

goodbye, I must go now.

(Control-d)

hostname% copy > data

hello, are you listening?

goodbye, I must go now.

(Control-d)
