Take a look at DmQuickSort. Of course you will have to pass a compare function (after all the OS doesn't know how to sort your specific structures), but DmQuickSort takes care of all the actual sorting. > Also the RecordInfo, this is only used if I want to set the record to busy or > whatever?

When using DmGetResource/Record the record will be set to busy automatically. > And last but not least, can I create 1 main record that has a list of > variables and have other records index this list? > (ie: record 1 has State names in it: Mass, NY, NJ.....) > > Can I tell my other records to have a index number into this record for the > state? Or is this something that shouldn't be done? Well, as far as the PalmOS is concerned you can put into your records whatever you want (<64k) and reference it whichever way you want. If you come from the desktop, think of a Palm database as some kind of directory containing files (records) which you can only access by index in the list, not by name, and which have a 64k limit.
