  @@@

YASM version 0.2.1
NASM version 0.98.36
Asm code in test is of type:

;comments ;comments ; ..... bits 16
org 0x100

section .text

BEGIN:

    mov etc, etc,

. . .

The following line works:

nasm /f bin -otest.com dazzler.asm
(produces test.com) The same invokation in yasm fails:
yasm /f bin -otest.com dazzler.asm

file.asm:17: label or instruction expected at start of line
NOTES:
1) nasm's /f obj or win32
produce the same error as yasm, however /f bin succeeds!

2) remarking the org 0x100 line allows yasm to produce
the correct test.com output.

  Initial investigation shows this to be a preprocessor issue.  NASM only defines

org as a macro when bin is used as objfmt (ditto with other objfmt-specific
macros). YASM does not currently have a mechanism for handling this;
unfortunately these are the kinds of issues that are hard to solve the "right"
way within yasm's framework of multiple preprocs/parsers/objfmts, as there's not
one single macro format that we can assume to be in use.

As a workaround, use [org 0x100] instead of org 0x100.

Assigning to NASM-compatible preproc (really should be "real" NASM preproc since
we're using the real one at the moment).

  A workaround has been implemented in r1.3 of modules/preprocs/nasm/standard.mac

in CVS. Leaving this bug open until a real internal fix is implemented, but in
terms of user visibility, this is fixed (e.g. ORG now works as expected).
