Specifying the option to free a resource

You can free a resource when you no longer need to use it by performing one of these actions:

Use the OPERATION=RELEASE and TOKEN=token parameters to free all resources associated with the specified token as shown in Figure 1.
Figure 1. TOKEN= specified on EDGXCI
```
***************************************************
** Done with the subcommand, setup release parmlist
***************************************************
  EDGXCI  MF=(M,RELPL,NOCHECK),PLISTVER=MAX,             X
        APIADDR=APIMOD@,OPERATION=RELEASE
 
***************************************************
** Call the DFSMSrmm API
***************************************************
  EDGXCI  MF=(E,RELPL,NOCHECK),TOKEN=TOKENA
```
Specifying TOKEN=TOKENA on the EXECUTE form of EDGXCI causes the 4-byte TOKENA area to be set to all zeros upon return from freeing the token.

TOKEN=token is required even when you specify MF=(E,label,NOCHECK), unless you also specify OPERATION=ENDALL. Specifying TOKEN=token causes the 4-byte token area to be updated upon return from the DFSMSrmm API. The token is set to all zeros by the EDGXCI macro expansion.
Specify the OPERATION=ENDALL parameter to free all resources associated with all tokens, as shown in Figure 1.
Rule: You are responsible for setting applicable tokens to all zeros when you specify OPERATION=ENDALL.
Your application program ends (end-of-task occurs).
