Edit Next Record Key 



The Edit Next Record key is used by most editing programs to find the next existing 

 record. It uses the index associated with the field the cursor is positioned in. If field 

 has no associated index the program will display an error message and take no action. 

 The program will find the first record greater than the data entered into the field. If no 

 record is found the fields are cleared and the cursor is positioned in the first field. The 

 program is then ready to add a new record or search for another existing record using 

 the Find, Next, or Previous Record keys. 



After finding the record the program will display the record and position the cursor 

 in the same field. Tj^jically the Find Record key is the F6 key. 



Edit Previous Record Key 



The Edit Previous Record key is used by most editing programs to find the existing 

 record less than the current record. It uses the index associated with the field the 

 cursor is positioned in. If field has no associated index the program will display and 

 error message and take no action. The program will find the first record less than the 

 data entered into the field. If no record is found the last record in the index is found. 



After finding the record the program will display the record and position the cursor 

 in the same field. TjqDically the Previous Record key is the F7 key. 



Edit Jump to Field Key 



The Edit Jump to Field key is used in editing programs to allow the user to move 

 directly to another field without having to go through the intervening fields. It uses the 

 Jump field in the Edit Dictionary to determine which field to go to. If no jump field 

 is defined no action is taken by the program. Typically the Jump to Field key is the F9 

 key. 



Edit New Window Key 



If an editing program has more fields than can be displayed on one screen or edits 

 more than one database at a time the New Window key will allow the user to bring up 

 another window with fields to be changed or added. If there are no other windows 

 available the program will take no action when the key is pressed. Typically the New 

 Window key is the FIO key.
