MOV BYTE PTR DS:[463315],EB not working?

As far as I know that is the correct ASM syntax, so when in Olly, I right click and choose Assemble and type in that (unticking NOP) and click ok but it comes up as unknown identifier? I'm probably making a silly mistake, but as far as I know that is how you write ASM in Olly.

That's worked but why the 0 infront of EB? I mean I can do 74 and 75 no problem so why do you put a 0 infront of EB, and will it still result in a straight jump been put into the address, or does the 0 infront of EB do something totally different.

I tried (with the same method) doing
JMP exenamehere.addresshere
but all it said was "Label expected", now I've had no problems doing this in Softice in the past, so what's happening?

I didn't assemble in OllyDbg, but in most known assemblers (MASM, A86, IDA) when hex number starts with a letter you always must put '0' before the letter to mark that the number follows, not the mnemonix

you use JMP exenamehere.addresshere

but you only have to use JMP addresshere

olly translates it with <exename> in front of address

(if your address is for example BB8877 and olly says "no memory at the specified address you have to insert 00BB8877 (8 Bit))

Ops no wonder I haven't had a reply in a while I forgot to post the following:

I just get a "Label expected" message now.
