<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Maybe you can have a look at the 'mxtb' utility of CISIS ? See the manual of CISIS.<br>
The parameter 'tab=' there allows adding up all occurrences of a field (as the required format).<br>
<br>
On the other hand, the original question for an equivalent of WinISIS' selection query
<br>
? p(v99)<br>
indeed cannot be handled well by CISIS because CISIS doesn't do this type of query (which are not based on the Inverted File but on a sequential scan of the database). In J-ISIS this 'sequential search' was introduced only recently (because it aims at mimicking
WinISIS fully).<br>
<br>
But you can work around that : e.g. you could create an index entry with the statement<br>
909 0 if val(v909)>0 then <span style="background-color:white">'Y' fi<br>
to select all records where v909 is present (as in ? p(v99) ).<br>
Or to see the actual number of occurrences in the index : <br>
</span>909 5 '/OC_/', if val(v909)>0 then <span style="background-color:white">f(nocc(v909),1,0) fi<br>
There is also a function RSUM() which sums all values of the occurrences of a field in one MFN. You can also use that in the FST format.<br>
Then the index terms identified by field 909 (or a dedicated prefix if you define one like here OC_) can be used to select all records with a non-zero value, which is even faster than
<br>
? p(v99).<br>
</span>
<div>and send the MFN's to Excel for statistics.<br>

<div>Thanks.<br>
However, it gives me the occurrence of every mfn, how can i format it to just give me the total of the occurrences for a tag for the whole database.<br>
<br>
Thanks<br>

<blockquote type="CITE">Good day,<br>
<br>
Use of mx command: How can I get the number of occurrences of a tag in a database, but it should just show me the total number of occurrences, and not display the contents. How can I then process those retrieved records which have data in the selected tags,
e.g. delete the mfns?<br>
<br>
<br>
In WInisis it is:<br>
<br>
? p(v99) <br>
? a(v34)<br>
? v99:'xxx' <br>
<br>
Thanks.<br>
<br>
