AndPic CATALOG
AndPic picVar [, row, column ]
Displays the Graph screen and logically “ANDS”
the picture stored in
picVar and the current graph
screen at pixel coordinates
(row, column) .
picVar must be a picture type.
Default coordinates are (0,0), which is the upper
left corner of the screen.

Returns the angle of expression1 , interpreting
expression1 as a complex number.
Note: All undefined variables are treated as real
variables.
In Degree angle mode:
