Hi Team,

I need to read last record from the file directly without reading each and every record and then reaching last record. Could you please tell me if this is possible using REXX program.

Thanks,
Harish

No. It is not possible. Other languages may depending on file organisation and capabilities of the language.

yes, invoke sort to reverse the record sequence of the file,
then read the output of sort.

first record read will be the last record in the originial file.

Garry - my reversing is so bad that that is when most of my little 'comings together' occur. Hopefully I can put all that behind me (ouch) and could be back in Dublin soon. Maybe bugging you again

but not sure where this proposed contract is but it smacks of the bank except it is contracted rate not salary like before.

As it happens - same bank, different area. Fingers crossed!

@harish: lets say u read ur file into a stem variable called filerec.
then the count of number of records read will be in filerec.0
now using the value in filerec.0 u can directly access the last record.

the point here is that YOU WILL NOT BE READING THE FILE IN REVERSE ORDER... instead u will be reading the entire file in one go and then accessing the last record.

The original topic is 8 years old !! Don't try piggy-backing on old posts - and, in any case, your question has nothing to do with the original topic. I fact, it belongs in a different part of the forum.

Analyse the dump for "A severe error (code X'0586') has occurred in
module DFHAPSI."
