# EinhugurChecksum.Crc16_MemoryBlock Method (console safe)

To compute a checksum using the Crc16 algorithm on a MemoryBlock then user the Crc16_MemoryBlock function. (Deprecated)

Crc16_MemoryBlock(
bytes as MemoryBlock,
offset as Integer,
length as Integer,
crc as UInt16) as UInt16

#### Parameters

bytes
  The bytes to calculate.
offset
  The offset where in the MemoryBlock to start. (First byte in the MemoryBlock is 0)
length
  The number of bytes in the memory block to do Adler32 checksum on.
crc
  The crc16 value to calculate from.

#### Returns

UInt16

#### Remarks

A good way to represent the checksum as an Hex string:
myString = Right("0000"+HEX(myCrc), 4)
This method is deprecated. Use the CRC16 class in CCITT mode to replace it.

- macOS Apple Silicon
- Windows 32 bit
- Windows 64 bit
- Windows ARM 64 bit
