BYTEx Assembler Operator

BYTEx operand

The BYTEx operators return the byte of operand corresponding to the position specified by x. For example, BYTE0 returns the least-significant byte, BYTE1 returns the next byte, and so on. The following table shows how the BYTEx, WORDx, HIGH, and LOW controls work on a 32-bit value.

The operand must either be absolute or a constant defined as extern :DATAn. Other types of relocatable operands are not allowed.

Note

• The BYTE0, BYTE1, BYTE2, BYTE3, BYTE4, BYTE5, BYTE6, and BYTE7 operators are available with the A166 Assembler.

Note

• This directive is available in the AX51 Assembler only.
