Hi,
I am trying to compare two files of 20 million rows using the batch ISRSUPC, the summary is shown below:
?104345 NUMBER OF LINE MATCHES 10000 TOTAL CHANGES (PAIRED+NONPAIRED
0 REFORMATTED LINES 10000 PAIRED CHANGES (REFM+PAIRED INS
10000 NEW FILE LINE INSERTIONS 0 NON-PAIRED INSERTS
10000 OLD FILE LINE DELETIONS 0 NON-PAIRED DELETES
?114850 NEW FILE LINES PROCESSED
?114850 OLD FILE LINES PROCESSED
Can anyone provide some input as what "?" stands for? |

How long did it take to run, out of interest?
The length of those number fields, including the ?, would be able to hold 9,999,999 - probably usually enough for a file comparison.
I agree with enrico. When the 10millionth arrived, the program cleverly noted that it couldn't be displayed, so when producing the totals it plopped the ? down to bring your attention to it. Probably somewhere deep in the manual it mentions file limits, and I guess you are lucky that this is the only apparent effect.
I'd not feel lucky. I'd split the files into three equal pieces and do the compare(s) again. I wouldn't want to "trust to luck" that half my file compared when I know "something" is "wrong" with the program for that half of the file. |

Or try with DFSORT compare and check how many new records and how many old records try to match the number with this number..
you will get to know what that ? means... |

using isrsupc for <application> dataset comparison is a bit of overshooting
application data is usually sorted on some key, most probably a <SORT> approach might be faster |
