Use the execute form of the IEEVARYD 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 IEEVARYD macro is written as follows:
| Syntax | Description |
|---|---|
| name | name: symbol. Begin name in column 1. |
| ␢ | One or more blanks must precede IEEVARYD. |
| IEEVARYD | |
| ␢ | One or more blanks must follow IEEVARYD. |
| OPERATION=operation parm | operation parm: RS-type address or register (2) - (12). |
| ,DEVICES=devices parm | devices parm: RS-type address or register (2) - (12). |
| ,NUMDEVS=num of devices | num of devices: RS-type address or register (2) - (12). |
| ,RESULTS=vary results | vary results: RS-type address or register (2) - (12). |
| ,CALLERID=caller id | caller id: RS-type address or register (2) - (12). |
| ,RETCODE=return code | return code: RS-type address or register (2) - (12). |
| ,RSNCODE=reason code | reason code: RS-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 IEEVARYD macro with the following exceptions:
list addr specifies the area that the system uses to store the parameters.
COMPLETE, which is the default, specifies that the system is to check for required parameters and supply optional parameters that are not specified.
