Name:
ASCII
.....ASCII text storing in memory
Format:
ASCII character expression {, character expression}*
character expression = character string | character constant | byte constant
Functions:
This instruction is used to store the ASCII character code in memory.
For the area reserved by this instruction, the ASCII text assigned by the parameter must be stored in
the memory. The character string for the parameter is decoded and stored in the memory sequentially
from low-order addresses.
The area size becomes the number of bytes for the decoded parameter. The operand is a character
string of one or more characters enclosed by double quotation marks.
The ASCII instruction stores the character code of each character of the character string in the
memory, however, since the information showing the length and the termination of the character
string is not output, the character strings may be set without a limitation.
Examples:
ascii "S1C88 Family"
ascii "bell",'\a'
;
bell and BELL code
ascii "bell\07" ;
Other format example
ascii "bell",'\07' ;
Other format example
ascii 62h,65h,6ch,6ch,07h ;
Other format example

Name:
PARITY
.....Setting/resetting of parity bit
Format:
PARITY <operand>
Functions:
The alphabet that has been adopted in the cross assembler asm88 is an ASCII character set. The ASCII
character data are indicated with 7 bits and the most significant bit shows the parity. This bit can be
optionally set or reset either always 0 or always 1 using the PARITY instruction. In addition, the total
number for 1 bit can be made odd or even. The following parities can be specified for an <operand>.
PARITY 7
Sets the parity bit at 0 (default)
PARITY 8
Sets the parity bit at 1
PARITY ODD
It is set such that "1" within the 8 bits becomes odd
PARITY EVEN
It is set such that "1" within the 8 bits becomes even
