Thanks Doug: Perhaps I can find out more information about the images in
question using their short or long crc values.

Subject: Re: What does CRC Stand For for Icon
You indeed have the correct definition of CRC. It was originally used
to protect data transfers, such as by modem, from errors by providing
a way to detect them. Nowadays a CRC has many uses, including as a
sort of ID for graphics in screen readers. Other similarly used
values would include checksums (older than the CRC) and MD5 hashes
(also called digests, I believe). The point of them all is to
represent a larger amount of data by a smaller one, for purposes of
identifying or verifying the integrity of the larger one.

Hi: I read a icon under the mouse and get the short and long CRC Values
spoken
I would like to know what the acronym "CRC" stands for- Googling it
comes up as "Cyclic Redundancy Check. A CRC is a type of check value
designed to catch most transmission errors."
Is this the correct definition as used in the WE Docs for Images and
Icons when speaking the short and long CRC values, numpad insert up
arrow 2 or 3 times.?
I also want to pick it up in my script to get a hard copy of the
diferent icon CRCs used in a particular window or WindowControl if
possible.
I haven't found anything in the Scripting Manual yet that will let me
do that so far unless I missed it.
Any ideas or pointers?
Thanks:
