dataOFFSET arg
The dataOFFSET macro generates an offset relative to the start of the group to which the DATA segment belongs. It is similar to the OFFSET assembler operator but automatically provides the group name. For this reason, it should be used instead of OFFSET.
arg
Specifies a label name or offset value.
The following example demonstrates the usage of the dataOFFSET macro:
mv ax,dataOFFSET label
