TAG Argument

Use the TAG argument in a LIST command to create an additional output field called TAG, which will be available in any segment generated by the command. This allows for the output from multiple LIST commands to be correlated back to the originating command.

In the following example, the command performs 2 LIST requests: one for the applications whose names begin with ABC, one for the applications whose owner ID begins with ABC. The returned records lists the TAG and the ADID. By checking the TAG, you can determine from which LIST request each record comes.
OUTPUT ADCOM FIELDS(TAG,ADID)
      LIST ADCOM ADID(ABC*) TAG(ABCAPPS)
      LIST ADCOM OWNER(ABC*) TAG(ABCOWNED)
Note: Any SELECT statements generated from a LIST statement using OPTIONS SELECT(Y) will automatically be passed the same TAG argument.
