Basic System Verification

Verification of the basic system normally includes these steps:

To operate from a 3270 display terminal, first log on through VTAM. To start a session, enter the logon APPLID. For example:
```
LOGON APPLID(ESF)
```
1. CA Spool prompts for a user ID and password. Enter the userid and password which is specified in CAIQPARM.
  When the session is successfully established, CA Spool formats the screen into a message-output area and a command-entry area.
2. Enter the display-file command. For example:
```
DF
```
  CA Spool responds to the display-file command with the message:
```
ESF840 QUEUE EMPTY
```
Run the supplied sample job IVPBPRNT to test the ESFPRINT utility in batch mode, to generate the first CA Spool file.
After the job has terminated, start the specified CA Spool printer. CA Spool starts printing the spool file if the printer setup matches the file setup.
To test the CA Spool to JES file transfer interface, enter the following:
```
RF1,ND=LOCAL  => ESF850   1 FILE(S) ROUTED 
RF1           => ESF850   1 FILE(S) REQUEUED
```
The file is copied to a JES2 or JES3 spin-off SYSOUT data set.
Run the supplied sample job IVPBJESX to test the automatic JESTOESF file transfer interface.
After the job has terminated, a new file starts printing on the specified printer.
To test the ESFPRINT/DSPRINT TSO command, start a TSO session:
```
ESFPRINT  DSN('CAI.CBQ4PARM(CAIQPARM)')
          DEST(destination) SUB(ESF) 
```
Specify the name of the test printer as the destination.
