Buffer / Move block

This command is used to move a specified block of data to a
new address within the current buffer space. Source address
block (or part of) will be filled by the blank character.

Buffer / Swap block

This command swaps the high- and low- order of byte pairs in
current buffer block. This block must start on even address and
must have an even number of bytes. If these conditions are not
fulfilled, the program modifies the addresses itself (start
address is moved to a lower even address and/or end address
is moved to a higher odd address).

Buffer / Erase

This command fills the content of the buffer with the blank
character.

The key <Ctrl+F2> is the hot key.

Buffer / Fill random data

If this This command fills the content of the buffer with random
data.

The reserved key <Shift+Ctrl+F2> is the hot key.

Buffer / Duplicate buffer

This command duplicates the buffer content in the source
EPROM address range to the address range of the destination
EPROM. For example, this command will copy the address
range of a 27C256 three times to fill address range of a
27C010 EPROM.

Note: The procedure always uses buffer start address 00000h.

Buffer / Checksum

The checksum dialog is used for calculate checksums of
selected block(s) in the buffer. The checksums are calculated
as such :


Byte

sum by bytes to "word". CY flag is
ignored

Word

sum by words to "word". CY flag is
ignored

Byte (CY)

sum by bytes to "word". CY flag is added
to result.

Word (CY)

sum by words to "word". CY flag is added
to result.
