Cardfile Screenshot and discussion:
The applet is built with several windows, each showing specific items.
Across the top is the menu, which is accessible with hotkeys, and below the
menu are action buttons.
On the left there is a list of the index fields found in the .CRD
file. The right side of the applet is divided into three vertical windows.
The top one contains the index field of the currently selected card. Immediately
below that is an editable area which contains the entry found in the data
section of the file. The bottom window is used to display some status information,
which is being used while testing out the program to see whether I have
the file data structures interpreted correctly. Some of the items in that
window: the total number of entries as found in the MGC header, the index
value of the current card, the string length of the index, and some values
calculated by the app to check the size of elements contained in the file.
You have several ways to look at a card - you can either step through
the cards using the <prev> and <next> buttons
or the Records/Previous and Records/Next menu items, or you
can click on the index of a record you want on the left side of the applet
window. The currently highlighted index entry is shown at the top of the
right hand side, and the data associated with it is show immediately below
