If a group variable is declared without length in assembly , for example

XYZ DS 0C
DS C12

then what is the meaning of declaring group variable without length.

(This was defined in a macro)

This is discussed here http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ASMR1003/5.19?SHELF=&DT=20000721044852

In this case, the usage is simply to assign a name to the following area. If the statement had been "XYZ DS 0F" then the usage would also be to force the following area to be fullword-aligned.
