Use the execute form of the IOCINFO macro together with the list form of the macro for applications that require reentrant code. The execute form of the macro stores the parameters into the storage area defined by the list form.
The execute form of the IOCINFO macro is written as follows:
| Syntax | Description |
|---|---|
| name | name: symbol. Begin name in column 1. |
| ␢ | One or more blanks must precede IOCINFO. |
| IOCINFO | |
| ␢ | One or more blanks must follow IOCINFO. |
| IOCTOKEN=ioctoken addr | ioctoken addr: RX-type address or register (2) - (12). |
| ,CSSID=cssid addr | cssid addr: RS-type address or register (2) - (12). |
| ,MAXMBI=maxmbi addr | maxmbi addr: RS-type address or register (2) - (12). |
| ,IOFACILITIES=iofc addr | iofc addr: RS-type address or register (2) - (12). |
| ,LINKAGE=SYSTEM | Default: SYSTEM |
| ,LINKAGE=BRANCH | |
| ,RETCODE=retcode addr | retcode addr: RX-type address or register (2) - (12). |
| ,RSNCODE=rsncode addr | rsncode addr: RX-type address or register (2) - (12). |
| ,MF=(E,list addr) | list addr: RX-type address or register (2) - (12). |
| ,MF=(E,list addr,COMPLETE) | Default: COMPLETE |
The parameters are explained under the standard form of the IOCINFO macro with the following exceptions:
list addr specifies the area that the system uses to contain the parameters.
COMPLETE, which is the default, specifies that the system is to check for required parameters and supply defaults for omitted optional parameters.
