I have been working, off and on, on Bible analysis programs.  This time I want to add a display of Hebrew characters in a richedit control, and finally succeeded.  I'm sharing a code demo of this, and a screen capture of the control (see attachment) with one Hebrew word, the first word in the book of Genesis.  I am by no measure an expert with this language - only a beginner.  Hope this is useful to someone.  -Jack Harris

Clever stuff - I like it...

In looking up the first few words of Genesis (I am not a religious person, by any means, but always happy
to learn new stuff), I came across this website, which was interesting:
