you can only write to the end of a file.  but it should be possible to keep
track of skips (deleted records) by using the record number from the file
information data structue, write a bogus record, read previous and delete
it to keep the positioning the same.

the output file would need to be update/add reusedlt(*no), the input file
should be seqonly(*yes 1) to insure the file information data structure
gets updated by each read not at block end, read the file non-keyed.

file.  Also, if line 2 is commented out, the program runs, but the record
numbers are assigned 1-10, not 5,10,15,20 as I would like.
