Use the execute form of the IOSCAPU 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 IOSCAPU macro with the CAPTOACT option is written as follows:
| Syntax | Description |
|---|---|
| name | name: symbol. Begin name in column 1. |
| ␢ | One or more blanks must precede IOSCAPU. |
| IOSCAPU | |
| ␢ | One or more blanks must follow IOSCAPU. |
| CAPTOACT | |
| ,UCBPTR=ucbptr | ucbptr :RS-type or address in register (2) - (12). |
| ,CAPTPTR=captptr | captptr :RS-type or address in register (2) - (12). |
| ,ASID=CURRENT | Default: ASID=CURRENT |
| ,ASID=asid | asid :RS-type or address in register (2) - (12). |
| ,LINKAGE=SYSTEM | Default: LINKAGE=SYSTEM |
| ,LINKAGE=BRANCH | |
| ,RETCODE=retcode addr | retcode addr : RS-type address or address in register (2) - (12) of fullword output variable. |
| ,RSNCODE=rsncode addr | rsncode addr : RS-type address or address in register (2) - (12) of fullword output variable. |
| ,MF=(E,list addr) | list addr: RX-type address or address in register (2) - (12). |
| ,MF=(E,list addr,COMPLETE) | Default: COMPLETE |
| ,MF=(E,list addr,NOCHECK) | |
The parameters are explained under the standard form of the IOSCAPU macro with the following exception:
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.
NOCHECK specifies that the system is not to check for required parameters and is not to supply defaults for omitted optional parameters.
