Command @...CLEAR Foundation
Positions the cursor and erases a screen area.
@ <nTop>, <nLeft> [ CLEAR [TO <nBottom>, <nRight>] ]
The screen command @...CLEAR erases an area of the screen by outputting blank spaces (Chr(32)) in the current default color. The cursor is then set to the position specified by <nTop> and <nLeft> and the functions Row() and Col() return these values. When the option CLEAR is not specified, only the screen row specified by <nTop>, from <nLeft> to MaxCol(), is overwritten with blank spaces. If the TO option is missing, blank spaces are output from the position <nTop>, <nLeft> to the bottom right screen corner.
