READING A CLARION FILE HEADER
SEE ADDITIONAL COMMENTS AT BOTTOM
Enclosed you will find the program "READHDR.CLA". This Program will
read a Clarion File Header and Display the information on the screen.
It will also print the information to the printer by pressing F10 on
the information screen. This will give you information on the start
of data, record length, Field information, etc...
The "include" file called "FILEDEF.CPY" is the Declaration file for a
Clarion Header. Note that it does NOT include the definitions for the
KEY part of the Header.
Also there is a "FILE2.DOC" which contains the complete documentation
for a Clarion File Header. Many thanks to the people at Clarion
Software for this information.

ADDITIONAL COMMENTS
The original version had some small errors in that the START of DATA was off
by 5 bytes and the offset of each field was off by 1 byte. The version here
has been modified to reflect this change. This data is espcially usefull for
users of Snow Report Writer.
Another question has come up in that the location of the delete flag was not
reported by this program (it still isn't). However, I think that the correct
location can be determined by subtracting either 3 or 4 from the START OF DATA
number. I have yet to verify this myself, but based on the information
supplied with this archive, I think that I am not too far off.
Any comments or suggestions on this, please drop me a note on the BBS. I hope
that this helps those who use it.
