you may use a tlist or tstringlist as your record-container,<br />
rather than an array, then u can use the customsort capability<br />
of this objects.<br />
<br />
just ask if you need advice about this.<br />

I think that I need some additional help. In &nbsp;Delphi help I can't find any reference to &nbsp;customsort. Is this available in Delphi 4?<br />
An example using &nbsp;multiple keys would be useful.<br />

I need a function that will sort an array of records, using multiple keys, i.e. similar to using <br />
ORDER BY customer_no, Inv_date, ord_number in SQL.<br />
<br />
The number of records in the array will not be very large, probably only several hundred maximum.<br />
<br />
Any guidance will be greatly appreciated.<br />
