| Register number |
XL1 |
The register number (X'0' to X'F') |
| Register Type |

Reserved |
| Total references |
FL4 |
The total number of references to the register for the assembly |
| Number of references |
FL4 |
The number of references to the register in this record
The groups of two reference fields below occur
n times depending on the value in this field. The reference
groups are contiguous so they may be treated as an array. |
| Offset of references |
FL4 |
The offset from the beginning of this record to the first group of
reference fields. A value of binary zeros indicates that there are no
references. |
| |
|
Start of reference groups, one group per reference.
The ellipses (...) indicate the fields are grouped. |
| ...Statement Number |

The statement number on which the register is referenced |

Note:
Where the number of references would exceed the record size for the
associated data file, the record is continued on the next record. The
continuation flag is set in the common header section of the record.
The current number of references (for that record) is stored in the
record and the record written to the associated data file. The next
record contains the subsequent references. The count of the number of
references is a count for the current record.
Fields that have been written will not be repeated in the next
record. Fixed length fields will be initialized to binary zeros or
spaces, and variable length fields will have a length of binary zeros. |
