Value is the line number you wish error messages to appear on. The runtime system pops up a one-line window on this line to display the message, and then removes it after the user responds. If this is set to a negative value, then the line used will be that many lines up from the bottom of the screen. For example, Error-Line=-2 implies that the next-to-last line should be used. The default value is -1. You may also specify the configuration variable SCRN_ERROR_LINE to set this value.
