HELP VEDREFRESHBLOCK A.Sloman May 1987 Refreshing an arbitrary rectangular block of text in a VED window. vedrefreshblock(<int:L1>,<int:C1>,<int:L2>,<int:C2>,<bool:dotail>) Keywords: VED refresh block L1,C2 represent a line and column in the VED buffer, as do L2,C2. The two positions are taken as opposite corners of a rectangular block of text to be refreshed. If dotail is non-false, then visible text to the right of the block will also be refreshed. Since the first four arguments are taken to be any two opposite corners of the block the following combinations are all equivalent: L1 C1 L2 C2; L1 C2 L2 C1; L2 C2 L1 C1; L2 C1 L1 C2 This procedure is useful for packages that implement windows occupying arbitrary rectangular portions of the screen, and for programs that insert or delete blocks of text which are not made of complete lines. It does not do anything about the indication of marked range on the left of the screen, as vedrefreshrange does.
