READPICTURE
This function is used to read in pictures, and store them in the TURTLE picture,
for example:
 	: READPICTURE();
 	: ****
 	: *  *
 	: ****
 	: ^D
.br
Notice that you have to type CTRL-D to tell READPICTURE
that you have got to the end of the picture.
We can now DISPLAY the picture read in:
 	: DISPLAY();
 	3****
 	2*  *
 	1****
 	 1234
.br
READPICTURE can be used in a disc file as well except that you
don't type a CTRL-D to terminate the picture but instead READPICTURE
takes the end of the file as the end of the picture, for example:
 	: CREATE SQUARE;
 	10: READPICTURE();
 	20: ****
 	30: *  *
 	40: ****
 	50:
 	:
.br
If you want blank rows in your picture and are using EDIT you will have a problem
because CREATE and EDIT assume you have reached the end of a file when you
type in a blank line; overcome this problem by typing in a line with just a space on it.

Until version 415 of POP11 you will have to type:
 	: LIB READPICTURE;
.br
before you can use the READPICTURE function.
