Do you have any info on the nature of cmd.exe's issues?

I wish I did. Here's what perldoc pl2bat has to say about it:

---8<---
4
      C:> ftype Perl=perl.exe "%1" %*
      C:> assoc .pl=Perl
      then
      C:> script.pl [args]

5
      C:> ftype Perl=perl.exe "%1" %*
      C:> assoc .pl=Perl
      C:> set PathExt=%PathExt%;.PL
      then
      C:> script [args]
---8<---
4 and 5 work on some Win32 operating systems with some command shells.
One major disadvantage with both is that you can't use them in pipelin
+es
nor with file redirection. For example, none of the following will wor
+k
properly if you used method 4 or 5:

    C:> script.pl <infile
    C:> script.pl >outfile
    C:> echo y | script.pl
    C:> script.pl | more

This is due to a Win32 bug which Perl has no control over. This bug is
the major motivation for pl2bat [which was originally written for DOS]
being used on Win32 systems.

To paraphrase, it doesn't work because it doesn't work. ;)

All I can see (from this and some searching of MSDN) is that redirection and pipes break when you use ftype and assoc to run a script. I have never seen a why. It's useful information, just not very informative.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or or How to display code and escape characters are good places to start.
