# Sample script which may be invoked via z/os Batch process, IE: BPXBATCH
# PATH statement needs to specify the absolute path to the java 'bin' directory.
# CLASSPATH must include the java encryption java client's absolute path and name. IE: /path/efclient.zip
# it is important to 'cd' to the directory where the efclient.zip file resides.
# Please note: This example utilizes decryption via PASSWORD.
# This example uses '/filesys/input.encrypt.file' as it's encrypted data source, which is also specified in BPXBATCH job as STDIN.
# This example uses '/filesys/output.decrypt.file' for expected decrypted output, which is also specified in BPXBATCH job as STDOUT.
# Important: Ensure the 'REGION=0M', parm is included in the BPXBATCH job step, to ensure the java virtual machine
#            has sufficient storage available.
