Assembler Pseudo-Instructions - Epson S5U1C62000A Manual

5.7 Assembler Pseudo-Instructions

The assembler pseudo-instructions are not converted to execution codes, but they are designed to control
the assembler or to set data.
For discrimination from other instructions, all the assembler pseudo-instructions begin with a character
"#" or ".". The instructions that begin with "#" are preprocessed pseudo-instructions and they are ex-
panded into forms that can be assembled. The expanded results are delivered in the preprocessed file
(.ms). The original statements of the pseudo-instructions (#) are changed as comments by attaching a ";"
before delivering to the file. The instruction that begins with "." are used for section and data definitions.
They are not converted at the preprocessing stage.
All the pseudo-instruction characters are not case sensitive.
The following pseudo-instructions are available in the assembler:
Pseudo-instruction
#include
#define
#macro–#endm
#ifdef–#else–#endif
#ifndef–#else–#endif
.align
.org
.page
.bank
.code
.bss
.codeword
.comm
.lcomm
.global
.set
.list
.nolist
.stabs
.stabn
The assembler supports the old-type pseudo-instructions shown above.
They are converted into the new format in the preprocessing stage. The LOCAL pseudo-instruction is
removed in the preprocessing stage. The END pseudo-instruction functions the same as the older tool.
