Use &SYSLIN_DSN in a macro definition to obtain the name of the data set to which the assembler is writing the object records when assembler option OBJECT, GOFF or XOBJECT is specified.
The local-scope system variable symbol &SYSLIN_DSN is assigned a read-only value each time a macro definition is called.
The value of the character string assigned to &SYSLIN_DSN is always the value stored in the JFCB for SYSLIN. If SYSLIN is allocated to DUMMY, or a NULLFILE, the value in &SYSLIN_DSN is "NULLFILE".
The value of the character string assigned to &SYSLIN_DSN is determined as follows:
| SYSLIN Allocated To: | Contents of &SYSLIN_DSN: |
|---|---|
| CMS file | The 8-character filename, the 8-character filetype, and the 2-character filemode of the file, each separated by a space |
| Dummy file (no physical I/O) | DUMMY |
| Punch | PUNCH |
| Labeled tape file | The data set name of the tape file |
| Unlabeled tape file | TAPn, where n is a value from 0 to 9, or A to F. |
The value of the character string assigned to &SYSLIN_DSN is determined as follows:
| SYSLNK Assigned To: | Contents of &SYSLIN_DSN: |
|---|---|
| Disk file | The file-id |
| Labeled tape file | The file-id of the tape file |
| Unlabeled tape file | SYSLNK |
Examples:
On z/OS, &SYSLIN_DSN might be assigned a value such as:
IBMAPC.OBJ
On CMS, &SYSLIN_DSN might be assigned a value such as:
SAMPLE TEXT A1
