You can get the records with their numbers using a DO - Chain, deleted
records will give "not found"  I have a small subrutine that gives the
total number of records in any file,  I can send you a copy.

Sample code:

F FileName  IU           Disk    /*  NO K */

C   1          Do    FileSize          RecN
C   RecN       Chain FileName
C              If    %found
C---- your process...
C              End...
