I'm not sure what are you asking? Do you understand what a GSAM file is?
There is nothing great with respect to GSAM files as they too are QSAM (flat) files. It's a batch processing access method for IMS that allows sequential files to be treated as IMS databases. So it all depends on the application whether you need to use the file as QSAM or GSAM - that means, GSAM itself is essentially a(n) QSAM file so your question does not stand on a practical ground, to start with!
