Identification data

Identification (IDR) data contains information about the module. The IDR data is not used during program loading and execution. A listing of the IDR data for a module can be obtained by executing the AMBLIST utility.

Link-edit or bind identification (IDRB)
IDRB data identifies the component that created the program module. IDRB data is associated with the entire module never in individual sections.
Translator identification data (IDRL)
IDRL data is produced by the language translator and identifies the compiler or assembler that produced the module or section and the date of compilation.
Zap identification data (IDRZ)
IDRZ data is created by AMASPZAP when it is executed against program modules. It contains a maintenance identifier (such as PTF number) and the date that the maintenance was applied.
User identification data (IDRU)
IDRU data is provided by the user on the IDENTIFY control statement for a program module. It can contain any information pertinent to the associated section. It is created at bind time using the IDENTIFY control statement. See IDENTIFY statement for more information.
