VSAM stands for Virtual Storage Access Method.it organizes
the records in a file in different formats for faster
accessing. various vsam datasets(files) structures are
KSDS(Key Sequential Dataset)
ESDS(Entry Sequenced Dataset)
RRDS(Relative Record Dataset)
we can read the Vsam Files
sequentially,randomly,dynamically(sequential,random) based
on the organization it refers.the following are the access
methods that we can perform on vsam datasets(files)
KSDS(sequential,random,dynamic)
ESDS(sequential,random)
RRDS(sequential,random)
