Hi,

We get some data from a GSAM file and we need to use certain information from this file to search a flat file and write out the records.

Is it possible to search the flat file without loading it into any internal array or table?

I am not able to make it out.

Not in any reasonable fashion.

If I understand your question correctly - what you wanted to do is compare GSAM file (based on few fields/records) with another file.

Is this correct? If so then you can do this using SORT.

If it is just to match the records from both the files and write the matched records from any file to the output, U can use SORT.

If u r using Syncsort, U can use the JOINKEYS option to do this..

however, if your requirement is to search the flat file. you may opt for loading the flat file into a working storage table (ofcourse iff the size of the file is not that large) to get it searched on the table.

DFSORT allows substring searches which search whole records for strings. I have a cobol program I use too in case I want to search multiple datasets. It's pretty fast enough for my needs.

Yes, but as the saying goes, "there is more than one way to skin a cat".....

Sure, if you will think about your requitements and be a little (a lot?) more descriptive of exactly what you are looking for.....
