  Searching on key segment in RMS indexed file? 
 The Question is:
 
Is it possible to search a rms file with a
segmented key using a substring
( not of the first key)
eg segmented key = surname + forename , and
search value(forename) = "John".
 
 
 
 
 The Answer is:
 
  Unless the target segment is a unique key in its own right, you are
  limited to a sequential search on the entire keyspace...
