Comparison between Perl and Ksh
he is concerned that we are using a technology unsupported by Sun.
Here are some more URLs for your boss to ponder:
The Basic Perl course that Sun Microsystems Inc. teaches
The Advanced Perl Programming Course that Sun teaches
Yes indeed Sun Microsystems makes money off of Perl the same way that O'Reilly and Associates and several other well known consultancies do (quality of instruction?). They also sell an "Operating Environment" that comes complete with Perl pre-installed. To assert that Sun does not support Perl is equivalent to asserting that Sun does not support C, C++, or Fortran. They do in fact support all of those programming languages (as well as ksh and another one that is quite highly hyped).
