Function SaveScreen() Foundation
Saves a screen segment as a character string.
SaveScreen([<nTop>], [<nLeft>], [<nBottom>], [<nRight>]) --> cScreen
SaveScreen() returns the specified screen segment as a character string. The character string contains the visible characters within the screen segment along with the accompanying color attributes. The function only saves character based, not graphic, elements on the screen.
The screen function SaveScreen() saves the visible characters in a screen segment along with their color attributes in a character string. Graphic elements are not saved. The visible characters on the screen are found as the odd numbered characters in the character string. The accompanying color attributes are in the respective even numbered positions. A saved screen segment can be redisplayed with the function RestScreen(). If no coordinates are specified, the entire screen area (0, 0 to MaxRow(), MaxCol()) is saved. This is identical to the command SAVE SCREEN.
