<p>Leslie,</p>
<p>I think I may have our solution. Look at this.</p>

<div class="moz-cite-prefix">Can you spot the difference?</div>

<div class="moz-cite-prefix">I have put a space in front of the

<div class="moz-cite-prefix"><br>

<blockquote>
<div class="moz-cite-prefix"><i>inside</i> <b>Select
Records between Labels</b></div>
<blockquote>
<div class="moz-cite-prefix"><i>inside</i> selects groups of
records whose first record follows a record that begins with a
specified string. The end of each group can be specified by a
count of records to select, or
as a string that must be at the beginning of the first record
after the group.
</div>
</blockquote>

<p>So while we have been chasing the delimiter character, all along
the stage and pipe were doing exactly what they should, with any
of the tested delimiters. In thinking about this, I was about to
suggest using the <i>between </i>stage<i>, </i>but it too works
with labels at the beginning of the records.</p>
<p>The suggested alternative in the CMS reference is:</p>
<p>
<blockquote type="cite">3. <i>pick</i> can do what <i>inside </i>does
and much more.</blockquote>
Unfortunately, the NetRexx <i>pick</i> implementation is
currently incomplete. That "much more" is a bear. We are lacking
the <i>from/to</i> options that we need here. Someday, I hope,
someone will -- since this is all volunteer driven open source
software -- improve our <i>pick</i>. Even if only incrementally.<br>
</p>
<p>At the moment, all I can suggest is in your <i>inside</i>
options to put in the exact number of SPACE characters to match
the file's records.</p>

I wonder, is NetRexx sensitive to the version of Java in use? I recently upgraded from
Java 18 to Java 19; is that significant?

I am not sure what is going on. If there is some setting in your system or
shell that is causing the problem. Could it not like the "/*"? (Or "like"
it too well?) I have not been able to duplicate the problem on my Windows
10 system in PowerShell. I'm not working with the full file -- I'm not sure
where/how to get it -- so first here is my test file, then the results from
your pipe, which was copy and pasted from your posting. PS

Are you getting some error message? No output with an abnormal return code?
