I think we're confusing a bunch of related items, as "screen" has been used to mean different things at different times in Xbase and Fox.
SAVE SCREEN TO <memvar> saves an memory variable of the text and colors of a DOS screen. Reverse engineering that format from .MEM files was the basis of a well-received article in FoxTalk October 1992 by a new-writer-to-the-Fox-world by the name of Ted Roche <s>. Screen variables, General Fields and .MEM files were favorite ways to blow up VFP while beta-testing new versions, as they are odd ducks and not always well supported by commands like ALLTRIM() <g> A data table type Picture was created for the Mac version of FoxPro 2.x, perhaps 1.x, but sadly my references for those days have gone to the great paper recycling center. SCREEN is also the name of the underlying background to the IDE, as in ACTIVATE WINDOW SCREEN _SCREEN is the VFP Object representing the updated version of that window, and an interesting place to hang additional things for global reference. CLEAR SCREEN as Bill points out, is how to clear that window.
