 VSAM files can be read and write same like cobol files. But only difference is you have to give the dsn path of your vsam file in jcl step while compile time.

  select empfile assign to dd1

  dd1 will have the dsn parameter with vsam file path.

try it

It is similar to the sequential read but here first a pointer is set and then the file is read from that particular record. For example:

START file name KEY >= file key ( Key of the VSAM file). After the pointer is set the file is read 

READ  file name NEXT

In PS files we can only do a sequential read but in VSAM we can do a random read and this is possibe by setting the key of the VSAM.
