<address1>: Start address of source area to be copied from; hexadecimal or symbol (IEEE-695 format only)
<address2>: End address of source area to be copied from; hexadecimal or symbol (IEEE-695 format only)

↵
... Copies data within the range from address 0x200 to address 0x2ff
to the area from address 0x280.

Notes
• All the addresses specified here must be within the range of the data memory area available with each
microcomputer model.
An error results if the input one is not a hexadecimal number or a valid symbol.
Error : invalid value (no such symbol / symbol type error)
An error results if the limit is exceeded.
Error : Address out of range, use 0-0xFFFF
• Write operation is not performed to the read-only address of the I/O area.
• Data in the write-only area cannot be read. If the source area contains write-only address, 0 is written
to the corresponding destination. If the destination area contains read-only address, the data of that
address can not be rewritten. If the source and destination areas contain I/O address of mixed read-
only bits and write-only bits, either read or write operation can be executed for the corresponding
bits.
• When the contents of the data memory is modified using the dm command, the displayed contents of
the [Data] window are updated automatically.
