I prefer to use a list format for databases that I do in text files.
possibly something like this (untested lingo!):
[ [#name:"Bohanen", #city:"Geneva", #salary:"4567"], [#name:"Klein",
#city:"Bern", #salary:"389"], [#name:"Meister", #city:"Lugano",
#salary:"9876"], [#name:"Correia", #city:"Basel", #salary:"7055"] ]
read in the entire list from the text file using standard FileIO.
reconstitute it as a list using
myList = value(myList)
then get at the data in the normal way you would for any list. this
makes things lots easier. the only problem is if it is a really big
list, then there can be difficulties. of course some may say that if
it is that big you should be using a real database! <grin>
