Snapshot v1.0 (C implementation)
Screenshot utility
Author: Bhuvanesh Bhatt (bbhatt1@towson.edu)
Platforms: TI-89 and TI-92 Plus
Last updated: September 24, 2001

Syntax:	Snapshot(filename)
Example: If you want to store the screenshot in "scrshot", use Snapshot("scrshot")

You can get screenshots from other screens too. For example, to get a screenshot
of the PrgmIO screen, do
Disp:snapshot("scrshot2")

The screenshots are stored in the usual PIC format, so you can view them either using
VAR-LINK (larger viewing area) or by recalling the picture to the graph screen using
RclPic scrshot

Please note that if you specify an invalid filename (such as "@"), you will still lose
the 3847 bytes and will not be able to access the picture (not from TI-Basic, anyway).

Plans:
Allow screenshots from most or all built-in applications.
Detection of invalid filenames.

Disclaimer:
Although I have tested this program before releasing it, I cannot guarantee that it
will not hang or crash. If it does hang or crash, reset the calculator:
		[2nd][LOCK][ON] on the TI-92 Plus
		[2nd][LEFT][RIGHT][ON] on the TI-89
If this doesn't reset the calculator, take out a battery, then press and hold [(-)][)]
while you insert the battery. I am not responsible for any damage to your calculator.
