ALIAS data type

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.

The alias data header is mapped by the TFMT_TDALIAS section of the IEWTFMT macro shown here.

Table 1. Transportable program alias data header
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: `Alias name length + Alias name + Alias AMODE length + Alias AMODE (2 bytes) (varying) (2 bytes) (varying)`
