I'm trying to use load inside a virtual block in Fasm 1 but I get an "error: value out of range". How can I get it to work? For example the following doesn't work

Code:

struc myStruc x
{
    .x  dw x
    virtual
        load myX word from .x
    end virtual
}

s myStruc 4

It only works if the virtual block is removed

Code:

struc myStruc x
{
    .x  dw x
    load myX word from .x
}

s myStruc 4

Virtual starts a new addressing space. Since the new space is empty then nothing can be loaded.

Code:

virtual
 dd 0x12345 ; this virtual address space is now 4 bytes long
 load x dword from $$
end virtual
