Just a suggestion, a "combo" makes possible to code fields in a single longint in place of pointers or pair of numbers table+field. Nice to put a field reference in json, for example. • decimal offset $combo_l:=($tableNumber*100000)+$fieldNumber ... $tableNumber:=$combo_l\100000 $fieldNumber:=$combo_l%100000 • bit offset $combo_l:=($tableNumber << 16) + $fieldNumber ... $tableNumber:=$combo_l >> 16 $fieldNumber:=$combo_l & 0xFFFF For my own I prefer the 1st, easier to read… and I don't feel concerned by max for table and field number - 32767 ;-) -- Arnaud de Montard ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
