- You probably have an older version of awk than the one documented in the 
book " The Awk Programming Language" by A. W. & K. . The one in the book
doesn't come with most unix systems. You have to buy it from ATT. They
also have a nifty tool I wish we could get which takes awk programs and 
writes c code. 

I haven't found a way to get older awk to read more than one file. Mostly
I get around this by using multiple awk programs that pipe output into 
each other.

If you are using GNU awk, eliminate the error by specifying a body for
the while loop. If you want no action, use ";", as in

gawk ' { while (getline <"lettre" > 0 ) ; } '

Additionally, if you are using Sun awk, I don't think you can use input
redirection with getline. The following runs without error in Sun awk.

awk ' { while (getline > 0 ) ; } '

Gawk is available by anonymous ftp from prep.ai.mit.edu (and many sites in
Europe as well.) I believe that to compile gawk, it is helpful to get "bison"
and "gcc", which are available from the same place.

"Sun awk" should probably be replaced by "old awk" in the above.

"Sun awk" is basically either BSD "awk" (which is basically V7-addendum-tape
"awk") prior to SunOS 3.2, or S5R2 "awk" in 3.2 and later (AT&T sped it
up a fair bit after the V7 addendum tape version came out).  (The only
Sun additions are minor null-pointer-dereferencing fixes and, as I
remember, a tweak to allow "-" to stand for "standard input" when used
as a program file name.)

GNU "awk" ("gawk") implements "new awk", which is the "awk" described by
the AWK book; AT&T also has a "new awk" implementation, available in
S5R3.1 and later and also available from the AT&T Toolchest.  SunOS 4.1
has AT&T's S5R3.1 "new awk" implementation (again, with
null-pointer-dereferencing fixes; too bad the damn 3B2 ABI for S5R4
doesn't forbid location 0 being part of the address space, if it did
maybe all those frigging null pointer dereferences in the porting base
source would get FIXED).

There is a translator called "awkcc" implemented at AT&T Bell Labs.
It speeds up the program drastically.

Yes.  There is one in the AT&T Toolchest called awkcc.  See my previous
post for Toolchest phone number and login.

Jon Bentley did some research on awkcc produced C programs and found the
C programs it generated were generally faster by an order of magnitude
than the awk input programs; however, there were a few instances where
the awk programs were faster.  Usually if there was a lot of i/o the C
program was faster.

Hmm, seems like someone should expand on this a little.

awkcc is a New Awk to C translator done in my center by
J. Christopher Ramming.  It is available from the AT&T Toolchest
(no, I don't know the price).

It should be fairly portable on UNIX boxes.  Don't know about other
OS'.  I know it's been used on BSD 4.3 [VAX and CCI Tahoe],
System V [3B2 and '386], SunOS [Sun 3 and Sun 4], and MIPS.

I feel obliged to post this email I received regarding awkcc from someone
who knows much more about it than I.

The author of awkcc Chris Ramming left AT&T for academia; I have no idea
if anyone is actively maintaining awkcc.

I have that tool but have never been able to get it to work.  It
requires, I think, an absolutely perfect C compiler to compile it.  In
particular, it makes heavy use of the pre-processor and was instrumental
in helping me to discover several bugs in mine.  Unfortunately, I have
an Altos computer and you know what that means!

Chris was away for a year, but he's been back since June (I think
that's when he got back).  Anyway, yes he's alive and well and living
(at least working) in Murray Hill.

It is true that there are problems with memory usage and pipes, but
Chris is (supposed to be) working on it.  In any event, he's still
maintaining it.
