Remarks
The Edit class provides simple text editing facilities for entering, deleting, and selecting text. In addition, you can specify if edit controls are to have a border, whether they should be read-only, or perhaps whether they should be password protected. Edit controls in this class hierarchy treat the text they contain as a series of numbered characters. In these edit controls, a selection is an ordered pair of character numbers. For example, if an edit control contains the text "samarkand," the selection (3,7) would select the text "mark." Also, for each control, the text limit is the maximum number of characters you wish the edit to hold. The non-graphic characters for newline (Chr(10)), tab (Chr(9)), and null (Chr(0)) occupy one character position.
