### CRC16 * Calcuate CRC16 Checksum

This program calculates the CRC-16 of a specified portion of a file (or the whole file). The idea is basically to be used in installation scripts that need to identify which version of a file they are working with to install different Slaves etc. The value it returns is the same as the CRC-16 calculated by resload_CRC16 which might be handy as well during Slave development.

#### Installation

copy it to C: or a similar place

#### Options

`FILE/A,OFFSET/K/N,LENGTH/K/N`
`FILE/A` | file to calculate checksum from example "S:Startup-Sequence"
`OFFSET/K/N` | start offset in file default beginning of file example "OFFSET=11264" to start at track 2 of standard disk image
`LENGTH/K/N` | amount of bytes to calculate the crc on default end of file example "LENGTH=1024"

#### Return code

The CRC16 is returned as the exit code of the program.
