Features of GMCKS
This is the first release of this utility.
It simply takes a straight binary file and adds the appropriate checksum.
It is possible that at some time in the future it will be upgraded
to process S19 and Hex files directly.
Command Line Switches
All optional processing is handled by supplying command line switch options.
Only an abbreviated form of the command line switch is required.
The minimum number of characters required for each switch is
indicated by the upper case characters in the following description
(eg for File=, just F= is required).
Either an equals sign (=), or a colon (:) can be used to to
separate the switch and its parameter.
|| Offset to store the 16 bit checksum result. The default is offset 6.|
|| Offset to begin calculating the checksum from. The default 8.|
|| Output file name. The default is the same name as the input file, meaning that the input file is overwritten.|
|| Force the basic help screen to be displayed.|
