Hi Mick, The doubleclick approach might give you some trouble, but there are several other ways this can be done. You could create a new pushbutton on a new or existing buttonpad (Create/Alter ButtonPad), you could add a new menu item to an existing menu or you could add a menu item to the right click menu for the map window (Alter Menu). You could also add a keyboord short cut to the menu so that the user would have a quich access to this menu.
Whenever the user activates this menu or button, you'll have to check whether there is an active selection of 1 record (use SelectionInfo(SEL_INFO_NROWS)) or several if you would allow this. You also have to make sure that the selection is made in the appropriate table (use SelectionInfo(SEL_INFO_TABLENAME)). After this you have to read the current value from the selected record(s) (use Fetch First From Selection and szCurValue = Selection.MYCOLUMN where MYCOLUMN is the name of the column holding the numbers). Now you are ready to show the read value in a dialog (Use Dialog, Control StaticText and Control EditText and CommandInfo(CMD_INFO_DLG_OK) to check if the user "okay'ed" the dialog). When the user has "okay'ed" the dialog you'll have to update the selection with the new value (use Update Selection Set MYCOLUMN = szNewValue) Note that I use another variable to hold the new value from the dialog, in this way I can check if the value was changed, if it wasn't changed it might not be worth updating the selection.
