Hi all,

Why c:DWORD does not compile?
Code:
        format PE CONSOLE
        include "win32axp.inc"

.code
main:
        ret


proc SomeProc c:DWORD
                        
        ret
endp

.end main

Picnic,

Are you afraid of "New thread" button? Wink

proc is a macroinstruction. By default, its arguments are separated by commas (yes, function name is argument too). Macro can parse arguments further, as defined by specification. This is the cause of your problem: «SomeProc c:DWORD» argument is split into «SomeProc» (name for function), «c» (calling conventions tag) and «:DWORD» (as a somewhat weird function parameter's name).

revolution,

Perhaps Tomasz should change calling conventions' tag to «cdecl» to avoid name clash. Wink

Or «ccall» and «stdcall» to match the macro names. With maybe aliases «cinvoke» and «invoke» also.
