&SYSLIN_MEMBER System Variable Symbol

Edit online
z/VSE®
The value of &SYSLIN_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 &SYSLIN_MEMBER in a macro definition to obtain the name of the data set member to which the assembler is writing the object module when the assembler option OBJECT, GOFF, or XOBJECT is specified.

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

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

Notes:
  1. If the OBJECT user exit provides the data set information then the value in &SYSLIN_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.
  2. The value of the type attribute of &SYSLIN_MEMBER (T'&SYSLIN_MEMBER) is U, unless &SYSLIN_MEMBER is assigned a null character string, in which case the value of the type attribute is O.
  3. The value of the count attribute of &SYSLIN_MEMBER (K'&SYSLIN_MEMBER) is equal to the number of characters assigned as a value to &SYSLIN_MEMBER. If &SYSLIN_MEMBER is assigned a null character string, the value of the count attribute is 0.
