Hi there,

Just started investigating LDM for use in our group for near real-time GPS 
data distribution and want to set up a Unix pipeline from my PIPE action 
in pqact.conf.  Can someone provide me with a syntax example?  I'm trying 
all sorts of combinations of the below:

EXP     ^(........\...)d\.Z$
        PIPE
        "uncompress  | crx2rnx - > /tmp/file.1"

Everything I try results in one form or another of  "No such file or 
directory".

--------------------
Nov 14 16:31:19 pqact[20380]:                pipe: uncompress  | crx2rnx - 
> /tmp/file.1
            pipe_open: 3 20383
            pipe_prodput: 3 maui317b.03d.Z
            pipe_put: 3
                pbuf_flush fd 3   4096 block
                 pbuf_flush: wrote  4096 bytes
                pbuf_flush fd 3   4096 block
|.Z: No such file or directory
crx2rnx.Z: No such file or directory
>.Z: No such file or directory
/tmp/file.1.Z: No such file or directory
        SIGCHLD
Nov 14 16:31:19 pqact[20380]: pbuf_flush (3) write: Broken pipe
Nov 14 16:31:19 pqact[20380]: pipe_dbufput: 
uncompress|crx2rnx->/tmp/file.1 write error
---------------------

Only just started playing with LDM yesterday.  Like what I see thus far.  
Hoping someone can help me out.

Thanks very much in advance.
