# Using Clojure on z/OS

- I think there is a huge opportunity to incorporate Clojure and the z/OS platform

- z/OS is for data intensive applications, Clojure does data very well

## Simple reading of a dataset and printing out

- wanted to see how hard it would be to read a simple PS dataset

- knowledge could be carried over to read from PDS members as well

- PS datset is located at `MYZUSER.TEST.PS`

- RECFM = FB, LRECL = 80

- compiled uberjar and SCP'ed to USS

- ran java jar via USS

- typical java cold start blah

```shell

/z/myzuser > java -jar hello-0.1.0-SNAPSHOT-standalone.jar

  file name: MYZUSER.TEST.PS

rec. format: FB

rec. length: 80
