<p><font face="serif">Some of you have reported that when you try to
run your lisp code as an executable it dumps into the SBCL
environment. I figured out what was going on.</font></p>

<p dir="auto" data-sourcepos="1:1-1:337">On cobra for some reason
some of the Lisp probrams think that they were created in a
Windows or DOS environment and have DOS end of line terminators
(Carraige return followed by a line feed). For that reason when
you run your code as a script it runs until it gets to the
carraige return and then the next character is a line feed which
dumps it into the SBCL development environment.</p>

command on your file you will get something like this...</p>
