I am wrote:

; section code

fsave fpuenv

; section data

fpuenv db 112 dup (0)



How can I do it ?

P.S.:
Sorry my English

1. fsave needs not memory address (eg. not number or label), but contents of memory (eg number or label in []s). This is really not very well explained in manual.

2. fpuenv label can't have assigned size (fpuenv rb 112), because this way, when you write "[fpuenv]", it means "byte [fpuenv]". So you must use ":", this way "fpuenv" doesn't have any size assigned, so "fsave" can use any size it wants.

fsave beheaves this strange because it requires very specific size, which doesn't have it's own operator.

PS: little english tutorial:
"I am wrote" -> "I wrote", "I have written"
"Sorry FOR my english"

2 vid:

Tnx.

P.S.:
-(eg. not number or label)-
eg. - ?

eg, ie,.... => 'for example'

You're wrong:

e.g. means exempli gratia, "For example".

i.e. means id est, "That is (to say)", "in other words", or sometimes "in this case", depending on the context. Never equivalent to exempli gratia (e.g.).

Tnx
