RECORD MANIPULATION COMMANDS IN FILE-AID


Record manipulation commands allow you to update file contents and to find and change occurrences of a string in a file.
 The record manipulation commands are:  
 INSERT    Causes "n" records to be inserted after the current record (not supported for BDAM files)                                   
 DELETE    Causes "n" records to be deleted beginning with current record (not supported for BDAM files)                                   
 REPEAT    Causes a record to be repeated "n" times (not supported for BDAM files)                                   
 FIND      Causes one or all occurrences of a string to be found    
 RFIND *   In Edit or Browse, causes the previous FIND command to be repeated
CHANGE    Causes one or all occurrences of a string to be changed          
 RCHANGE * In Edit, causes the previous CHANGE command to be repeated    
 SAVE    * Causes the data to be stored back into the edit dataset  
 UNDO      Causes the last applied change to data to be reversed       
 When using an XREF to work with "segmented" records the following are valid:
 ADD       Insert a segment at a point in the record.                       
 NEXT      Display NEXT segment of record using correct layout              
 REMOVE    Remove a segment at a point in the record.                       
 TOP       Return to start of record and display base                        
 USE       Display layouts and allow manual selection and relocation
