<p>In building a new <b>HELP</b> stage, and wanting to handle all
the stage names and their synonyms, I have run into a problem with
an argument of just the question mark: "?", which is a synonym for
<b>HELP</b> in CMS.</p>
<p>Here are the first few lines traced. First with the character <b>></b>
which is processed all right. But with the character <b>?</b> ,
it never gets through.<br>
</p>
<div style="display:inline-block;white-space:pre;background-color:#012456;font-family:'Cascadia Code',monospace;font-size:10pt;padding:4px;"><span style="color:#D3D7CF;background-color:#012456;">PS C:\Users\Jeff\Documents\nr\netrexx-code\examples\pipes> </span><span style="color:#FCE94F;background-color:#012456;">pipe </span><span style="color:#06989A;background-color:#012456;">"ahelp >"
</span><span style="color:#D3D7CF;background-color:#012456;"> --- ahelp.nrx [Thread-1,njPipes]
25 *=* method run()
26 *=* data = Rexx ""
>v> data ""
28 *=* parse arg() stage_to_help
>v> stage_to_help ">"</span></div>
<p></p>
<div style="display:inline-block;white-space:pre;background-color:#012456;font-family:'Cascadia Code',monospace;font-size:10pt;padding:4px;"><span style="color:#D3D7CF;background-color:#012456;">PS C:\Users\Jeff\Documents\nr\netrexx-code\examples\pipes> </span><span style="color:#FCE94F;background-color:#012456;">pipe </span><span style="color:#06989A;background-color:#012456;">"ahelp ?"
</span><span style="color:#D3D7CF;background-color:#012456;"> --- ahelp.nrx [Thread-1,njPipes]
25 *=* method run()
26 *=* data = Rexx ""

<p>Some exploration with raw NetRexx shows the Shell does not like
passing <b>></b>, but all is right with<b>?</b>:</p>

<p>So, NetRexx alone is not "eating" the "?" parameter, it must be
Pipelines that is.</p>
<p>Is this a feature of Pipelines that I have missed, or a bug?</p>
<p>Anyone's help would be appreciated.</p>
