Sorry for my bad english.

I tried to add "data tls" directive, to put TLS rva and size to PE header. First, I added new formatter symbol "tls":
Code:
formatter_symbols: 
...
 db 3,'tls',1Ah,5
 db 0  
    

But it does not work:
Code:
flat assembler  version 1.60
tls.ASM [11]:
data    tls
error: undefined symbol.
    

Can you tell me, how to add my own formatter directive?

The table of formatter symbols (do not mistake them with formatter directives, they actually reside in the instructions table) has to be sorted alphabetically, so you must put it into correct place into table.

However for this kind of modification is not necessary at all for your purpose, since "data" directive allows number as a parameter, too. You can do it this way:
Code:
TLS = 5

data TLS
; ...
end data

Oh, right. So you should have written:
Code:
db 3,'tls',1Ah,9    

if you really wanted to add it as a formatter symbol.
