Actually when I tried your code in gawk, I did not get any terminal output. That may be because gawk buffers its output. So, the file for_later.txt actually has records only when the program finishes (or when the buffer is flushed) and not in between.

But, I could simulate the behaviour mentioned by you by putting in a system call with a null string (system("")) after print $0 > "for_later.txt". This flushes the output buffers to their destinations.

When I tried your code with the awk which comes with AIX 6.1, I got what you want to see:
Code:
book # 001|1|America|Price:   $
book # 002|56|Asia|Price:   $
book # 003|38|Europe|Price:   $

bibledit-rdwrt

BIBLEDIT-RDWRT(1)					      General Commands Manual						 BIBLEDIT-RDWRT(1)

NAME

       bibledit-rdwrt - Read or writes data to or from a Bibledit-Gtk Bible or project

DESCRIPTION

       Bibledit-rdwrt can read from or write to Bible data.

       Syntax: bibledit-rdwrt -r|-w project book chapter|0 fileName

       Breaking the syntax down we have:

       First parameter: -r|-w This can be either -r or -w which determines whether the remaining arguments are going to do a "read" operation from
       the specified Bibledit-Gtk Bible / project, or do a "write" operation to that Bible / project.

       Second parameter: project This gives the name of the Bibledit-Gtk Bible / project.  All we have to do is ensure that the  project  name	we
       want to access is a valid/existing one.

       Third  parameter:  book This is simply the 3-letter book code for the Bible book that is being read/written to.	I.e., MAT for Matthew, GEN
       for Genesis, etc.

       Fourth parameter: chapter|0 This can be either a chapter number or 0 (zero) for reading/writing	either	an  individual	chapter  or  read-
       ing/writing a whole book (when the parameter is 0).

       Fifth  parameter:  fileName  This  is a temporary file name that we assign for our use with bibledit-rdwrt.  For a read (-r) operation this
       fileName argument is the name of the file that will be created by bibledit-rdwrt containing a copy of the whole book (corresponding to  the
       3-letter  code),  or  that  contains the individual chapter contents (of a designated chapter) of an existing Bibledit-Gtk book file in the
       Bible / project. It should be prefixed with a path us.  Since bibledit-rdwrt is a console operation, after AdaptIt calls it using  ::wxExe-
       cute,  it would need to read the resulting temporary file to grab the contents for its use.  For a write (-w) operation this fileName argu-
       ment is the name of the temporary file that bibledit-rdwrt reads to get the text which it then writes to the appropriate  Bible	/  project
       file.   The  temporary  file  can contain the text of a whole book, or just the text of a single chapter for the book specified by the book
       3-letter code and the chapter (number) argument.

       bibledit-rdwrt may exit with 0 on success, or -1 on failure, as it sees fit.  It may write to stdout or stderr, as it sees fit.
