### 7.92 `.struct expression`

Switch to the absolute section, and set the section offset to expression, which must be an absolute expression. You might use this as follows:

            .struct 0
    field1:
            .struct field1 + 4
    field2:
            .struct field2 + 4
    field3:

This would define the symbol `field1` to have the value 0, the symbol `field2` to have the value 4, and the symbol `field3` to have the value 8. Assembly would be left in the absolute section, and you would need to use a `.section` directive of some sort to change to some other section before further assembly.
