segNameOFFSET arg
The segNameOFFSET macro generates an offset relative to the start of the group to which the user-defined segment segName 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 segNameOFFSET macro:
mv ax,initcodeOFFSET label
