This command is used to recall (open) a picture you have saved on your calculator. This is normally used in programs, because you can open pictures from the graph when you are not running a program. It is very useful for sprites as well, as it can recall a picture variable on top of a background, without deleting any of the background. In a program, however, you can recall a different picture for a different input, as shown below:
:If a=16 :RclPic 2 :Else :RclPic 3
260 - Domain error happens when the [row][,column] argument is outside the screen range..
960 - Undefined variable happens when the picture variable specified does not exist..
