Bernard,
 
wrt your subject line - I suggest you try sending such notes to
alt.pot.smoke or the likes.
 
Just kidding - whether intentional or not I appreciated the irony.
Sometimes my SAS coding makes me feel delirious too  ;-)
 
Regards,
Mark DeHaan

Subject:  Wrong stuff in pipe ???
 
 
 
 
Hi,
 
        I'm trying to read a compressed SAS file directly from SAS.
I tried the sample program from SAS institute but I get error messages.
I first created the named pipe in my home, then I compressed a small SAS
file
 (named work1.pipe).
 
Here a sample of what I get from the LOG:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~
98     libname compr  '~/named_pipe';
NOTE: Libref COMPR was successfully assigned as follows:
      Engine:        TAPE
      Physical Name: /home/bernard/named_pipe
99     filename nwrpipe pipe 'uncompress > ~/named_pipe <
/work1/pipe.ssd01.Z
 &';
100    data _null_;
101     infile nwrpipe;
102    run;
 
NOTE: The infile NWRPIPE is:
      Pipe command="uncompress > ~/named_pipe < /work1/pipe.ssd01.Z &"
 
NOTE: 0 records were read from the infile NWRPIPE.
NOTE: DATA statement used:
      real time           4.510 seconds
      cpu time            0.106 seconds
 
 
103    data new; set compr.pipe;run;
ERROR: The record formats are different.
 
NOTE: The SAS System stopped processing this step because of errors.
WARNING: The data set WORK1.NEW may be incomplete.  When this step was
stopped
 there were 0 observations and 0 variables.
WARNING: Data set WORK1.NEW was not replaced because this step was stopped.
NOTE: DATA statement used:
      real time           1.120 seconds
      cpu time            0.075 seconds
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

        From the message I have, I understant that SAS is expecting
something
that would be created with the TAPE engine.  It is not the case, this is a
standard disk file I compressed with Unix compress command.
 
        I tried to rename the named pipe like a SAS datasets to fool SAS
and
make it think the pipe is a SAS file.  This don't work either... SAS give
me
the following message:
 
WARNING: File '/home/bernard/npipe.ssd01' is shorter than expected.
109    data new; set compr.npipe;run;
ERROR: Invalid header on file COMPR.NPIPE.DATA.
 
 
        Is the example from SAS institure wrong or am I missing something
???

                Bernard Tremblay
