Hi Craig,

1.) I have a slight improvement on the code suggested by News

try

Data _null_;
    file _webout;
    infile yourfile; /* your file */
    /* input _text_ $200.;    take that out */
    put _infile_;  /* change this */
run;

This should give you an advantage because it transfers one record at a time
from the input buffer directly to the output buffer
without loading the data into the PDV.


2.)  Your

x 'cat "/home/craig/file.html"';

should be really fast, but it doesn't work with SAS/Intranet ! Hmmm ... have
you set    options noxwait;   ???? Try it!


Ciao.
Mauro Morandin
