[lazarus] "Variant" variable ?

[dvortex]

2 things:

Where is TVarRec declared ?
(so i can start from there and overload it ... --hehehe i love that
word--)

Can someone tell me if this is correct:

Load typinfo.pp from ./rtl/objpas.pp
go to line 90
this is the declaration of a type called TTypeData (if i read this right).
The first line under (line 91) is a case statement (sort of like what i
asked earlier). i do not understand how this works. it doesn't make any
sense to me. i visualize this as having a record that has different
property depending of the value of one.

for instance, if mastervalue is "175" then there will also be a property
called "subvalue" of a certain type, which would be different is
mastervalue had a different value. In this case (the typinfo.pp), i don't
see the "mastervalue" element/property... 

someone care to spend some time to explain to me this ?

Thanks :o)
