Several architecture definition statements are used to identify the outputs of a build. These statements are: ALIAS, COMP, LIST, LMAP, LOAD, OBJ, and OUTx. These statements have two parameters. The first is the member name of the output and the second is the type name of the output. The type name parameter must be a type name from the project definition. The member name parameter can be either a valid PDS member name or an "*". A PDS member name can be used when there is a single output with a predefined member name. PDS member names must be used for the ALIAS and LOAD architecture statements. An "*" must be used if there are multiple outputs or the output member name is not predefined.

Build allocates temporary data sets to hold the outputs generated by the build translators. If all the translators complete successfully the outputs from the temporary data sets are copied into the SCLM hierarchy. Because the copy does not take place until all translators have completed, the allocation of the output data sets must be retained without overwriting the output until after the last translator runs.
