pipe breaking

Hello,
 I am a relatively inexperienced UNIX user, and I would appreciate
 any advice on the following problem:

 I have some rather large data files stored on disk in compacted form.
 I use ccat and a pipe to feed the data file to a plotting program.
 This fortran program accepts the uncompacted data from standard input
 via an unformatted read statement and plots it; it exits from the
 plotting loop when an EOF condition is detected.  At this point I
 want the program to accept input from the keyboard; however, it 
 continues to read from the pipe.  Do you have any advice on how I
 can redirect the input once the EOF is reached?  Thanks for your support.
