Can you describe the structure of the logicUser.lst file and *.lgc files?

What I have been able to analyze so far...

1. From which areas of the file is CRC32 counted?
2. Is the space between LOGIC_FILE_HEAD and LOGIC_ITEM reserved for the future?
3. Can the space between LOGIC_FILE_HEAD and LOGIC_ITEM have random content?
4. How exactly is CRC32 calculated?

CRC32 is all LOGIC_ITEM+LOGIC_VECTOR .The initial value is 0

Something is wrong with this CRC32 ...
In the "4052.lgc" file shown, the selected area is LOGIC_ITEM+LOGIC_VECTOR. The counted CRC32 is at the bottom and is different from that in the file?!?

Please describe to me the CRC32 counting process in more detail. This will allow me to better use the potential of this programmer as a logic tester, because you do not want to add the additional functions I have proposed (import / export to text files, http://forums.xgecu.com/viewthread.php?tid=185&extra=page%3D1).

I would also be interested in either more information about the format of the LST file, or a tool that allows you to IMPORT vectors.
