PROGRAM-NAME
The DISPLAY/CLEAR F16 key works as follows:
 Pressing F16 alternates the values of the screen between those
 most recently read or written, and a set of initial values.
Read by key (FIRST/EXACT/APPROXIMATE/GENERIC) works as follows:
 The key field in which the cursor is positioned is selected to 
 be the retrieval key, using the entered value, if any. If the 
 cursor is not positioned in a key field a read by the default key
 for this record will be assumed. (For READ FIRST the value
 in the key is ignored.)
Read Next retrieves the next record within the subset
 established by the prior "Read by Key" operation.
The UNDO key can be used to reverse the last modification to 
 the database, so long as no intervening READ, INSERT, DELETE
 or update has been requested.
Press shift F16 to return to Record display, or F3 for more help
