An ALIAS data type indicates that the data is
an alias name. For the alias data type, the alias name and AMODE are
stored after the data header. Figure 1 depicts
the format of the alias data type. The alias data header is mapped
by the TFMT_TDALIAS section of the IEWTFMT macro and shown in Table 1.
Figure 1. Alias data record
The alias data header is mapped by the TFMT_TDALIAS section of the IEWTFMT macro shown here.
| Name | Description | ||
|---|---|---|---|
| TFMT_TDALIAS | DSECT | Maps the alias data header | |
| TFMT_TDALIAS_EYE | DS | CL8 | Data record identifier. Contains string 'IEWTLIAS'. |
| TFMT_TDALIAS_LVL | DS | FL1 | Level number: 1 |
| TFMT_TDALIAS_RS1 | DS | CL3 | Reserved |
| TFMT_TDALIAS_LEN | DS | FL4 | Length of the record including the varying data |
| TFMT_TDALIAS_EPOFF | DS | FL4 | Alias entry point offset. The offset is relative to the beginning of the program object that contains this alias. |
| TFMT_TDALIAS_DATOFF | DS | FL2 | Offset to the alias data relative to the beginning of the alias data record |
| TFMT_TDALIAS_RS2 | DS | FL2 | Reserved |
Note: The varying
alias data is stored immediately after the TFMT_TDALIAS data header.
The alias data linear format is:
