z/OS Communications Server: SNA Programming
SC27-3674-00

You can code any of the following expressions:

A register number or label of an EQU instruction for the register number, enclosed in parentheses. For example:
```
         MODCB RPL=RPL1,ARG=(REG5),AM=VTAM
         ⋮
REG5     EQU   5
```
Note: This form is prohibited if you are using the “simple” list form of the macroinstruction (MF=L).
An expression of the form (*,expr) as explained in the preceding section. The address specified by expr is indirect; that is, it is the address of a fullword that contains the value. For example:
```
         MODCB RPL=RPL1,ARG=(*,NEWCID),AM=VTAM
         ⋮
NEWCID   DS    F       NEWCID SET DURING PROGRAM
*                      EXECUTION
```
