Assembly-language instructions can be written in the range between
_ _asm { and }. This range is called an _ _asm block afterwards.
The language specification in the _ _asm block is described below.
1. Syntax
<assembly-language instruction string>
• The compiler regards an _ _asm block as a statement of
• Up to one instruction can be written in one line.
• One instruction cannot be written across multiple lines.
• A colon, ‘:’ is necessary right after a label.
• A local label which begins with a ‘?’ is not allowed.
• The comment in the C/C++ language format (/* */ and // ) is allowed.
• Any comment in the _ _asm block is not displayed in the assembly
• Except the .DATA directive, any assembly directives cannot be written.
...
outside a function or before the declaration in a compound statement
of C language.
In the assembler, writing the ‘+’ sign at a predetermined position allows
to continue the current line to the next. In the _ _asm block, however,
the ‘+’ sign is ineffective.
The assembler regards a symbol beginning at the first column as a
label. In the _ _asm block, however, an instruction can be written from
the first column. For the compiler to recognize a label in an _ _asm
block, a colon, ‘:’ is necessary.
The comment in the assembly language format (; ) is not allowed.
source output or in the object listing output.
File inclusion, conditional assembly, macro and structured assembly are
not supported.

where a statement can be written, the block cannot be written
