<p>Leslie and Mike and All,</p>
<p>The WORDS option of the SPECs stage is supported in NetRexx
Pipelines. FIELDS, and the SEPERATORs are not yet. (WORDS uses a
simple PARSE, but using a non-SPACE separator will require more
code, probably PARSE in a loop.)</p>
<p>These stages are in the test files (specs_tests2.njp) and work:</p>
<p>-- specs words space range</p>
<p>specs words 2-4 1 | </p>
<p>-- specs words no-space range</p>
<p>specs words2-4 1 |</p>

Hmm... no, that looks quite similar like the first case, so this
one too I will not convert to NetRexx Pipelines. But the third
pipe is worth it:
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">call RxPipe '< "' || fn || '"!l fs ; f1!stem loc.!spec fs 09 f1
1!stem n.'
</pre>
</blockquote>
</blockquote>
<pre class="moz-quote-pre" wrap="">
No-no-no-no:
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">Error (specs) - fs 09 f1 1 write - Unrecognized option: fs
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
A quick glance into the documentation reveals:
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">(3) CMS only. Not yet implemented in NetRexx Pipelines
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
Therefore this OS/2 pipe is converted to plain ooRexx without
support from NetRexx Pipelines. Same for next one:
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">if syswinver() = 'WindowsNT 6.01' then, /* Win7 only */
gehon = '< C:\Windows\System32\drivers\etc\hosts', /* mappings of
dotIP to host names */ '!spec fs # f1!strip!l!spec w2!'
/* keep name only */ else gehon = ''
call RxPipe gehon 'literal localhost!stem honam.' /* no sort as
ComboBox will do so */
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
Again spec fs char is the show-stopper. Next one?
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">selni = ctlcbx~selected
call RxPipe '(end ?) var selni!a:lookup f1 master!spec f2',
'!spec fs ; f1!strip!var fid!reverse!spec fs . f1!reverse!xlate!var
sfx', '?stem loc.!a:'
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
Forget it, no way! Two times spec fs ... Next one is:
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap=""> call RxPipe '(end ?) var fid!strip /"/!get asis BIN',
'!a:take 16 bytes!spec *-* c2x!var sig',
'?a:!b:take 4 bytes!reverse!spec *-* c2x!var kml',
'?b:!stem rst.'
</pre>

<pre class="moz-quote-pre" wrap="">
Finally, the perfect candidate for NetRexx Pipelines, read a file
binary, sip off two strings from the beginning, convert and
deliver them to ooRexx, also the untouched remnant of the file for
further investigation. New thereby, maybe a challenge, are the two
strings and an unknown number of records returned.
But first I'll "rexxify" all skipped before I attack this one.
/M.
