<p>Alternatively one can also put, instead of leading spaces, '$$' as indicators, at least that is what I have seen in other MARC-records. Probably that is for the same reason.</p>
<p>On the other hand, if you use MARC and therefore subfields (all the time), you have to refer to ^a explicitly in your PFTs, and then whether or not there are preceding indicators and/or spaces does not matter too much. But it matters when referring to a
substring of that field, e.g. v245*2, since then fixed positions are used.</p>
<p>Otherwise dropping the line $val=$trim(val); only deletes the leading and trailing spaces (as a standard PHP-function), so it is not too much harmful.<br>

<p style="margin-top:0; margin-bottom:0">Dear colleagues,</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">When you import records using Z39.50 ABCD works fine; also if you are using a conversion table. But: if you import MARC records there may be a problem when you are using a conversion table, i.e. leading spaces are deleted
(not when you are NOT using a conversion table: then the leading space are kept). The thing is that leading spaces have a meaning in MARC: they are empty endicators, e.g.</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">300: ^a789 pages :^billustrations, ^c23 cm</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">In this field the two indicators stay empty, i.e. they are represented by spaces. In the next example the first one stays empty:</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">264: 1^aLondon :^aMacmillan,^c2009 [here only the second indicator is used, so it is important that then "1" is not moved to the first position]</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">In contrast to this, in the next example the two indicators are not empty:</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">245:12^aA new marketing strategy [etc.]</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">In order to keep the spaces when using a conversion table you should delete this line in the script z3950_copy.PHP:</p>
<blockquote>
<p style="margin-top:0; margin-bottom:0">$val=trim($val);</p>
</blockquote>
<p style="margin-top:0; margin-bottom:0">All this under the condition that there is no other situation where you would need to remove the leading spaces when using a conversion table. Does anyone know of such a situation? If not, it could be better to remove
the code line above from the z3950_copy script permanentely in future distributions of ABCD.</p>
