LF Index Entries and QUSRMBRD

I am writing a balancing/checksum program, and there is an account file (PF) 
with a date field. I want a count of all records where this date field isn't 
*LOVAL. I could simply create an LF, then read and count the records, but I 
notice that, once I create the LF, I can DSPFD it, and get the 'Number of 
index entries' from the display. So I want my program to use an API to get 
this info, and avoid any File I/O. 

I looked at QUSRMBRD, and I see the Current number of records field in the 
MBRD0200 format, but this is not what I am looking for. Has anybody else 
accomplished this, perhaps with a different API?
