ErrStr

PrintF( "Program exiting: %S%E", ErrStr )

The global String variable "ErrStr" in the MUX-Window Action! library is a string to check when a library call fails. For example, if you try to open a window, but you cannot, you might want to know exactly why. (Not enough memory on the server? Bad location or size for the window?)
