z/VSE

The value of &SYSTERM_MEMBER is always null.

The value of the type attribute is O, and the value of the count attribute is 0.

z/VM and z/OS

You can use &SYSTERM_MEMBER in a macro definition to obtain the name of the data set member to which the assembler is writing the terminal records.

The local-scope system variable symbol &SYSTERM_MEMBER is assigned a read-only value each time a macro definition is called.

If the data set to which the assembler is writing the terminal records is not a z/OS partitioned data set, &SYSTERM_MEMBER is assigned a null character string.

Notes:

If the TERM user exit provides the terminal data set information then the value in &SYSTERM_MEMBER is the value extracted from the Exit-Specific Information block described in the section "Exit-Specific Information Block" in the HLASM Programmer's Guide.
The value of the type attribute of &SYSTERM_MEMBER (T'&SYSTERM_MEMBER) is U, unless &SYSTERM_MEMBER is assigned a null character string, in which case the value of the type attribute is O.
The value of the count attribute of &SYSTERM_MEMBER (K'&SYSTERM_MEMBER) is equal to the number of characters assigned as a value to &SYSTERM_MEMBER. If &SYSTERM_MEMBER is assigned a null character string, the value of the count attribute is 0.
