I wonder... (Antonio, ChatGPT is not accessible, to much hits at this time )))))

When a dbf is on a record I have the (BAD) habit of doing calculations like :

                     nAankoop = artikel->new_bruto -  (artikel->new_bruto * artikel->korting)/100

                     nAankoop = nAankoop -  (new_bruto * artikel->korting2)/100

                     replace artikel->new_aankoop with nAankoop

                     artikel->new_marge = ((artikel->new_bruto/artikel->new_aank)*100)-100

                     artikel->new_diff  = ((artikel->new_aank/artikel->aankoop)*100)-100

will there always be a disk access for each time I use a item artikel->.... ? or will the data come from the cach of the computer ?

Just to be sure ! . I can easily change my workflow in using a hash or tdatabase for this.

Dear Marc,

I would say that the data come from the cach of the computer

Only when you move to a different record, or you modify the data, the disk will be accessed
