The overwrite statement lets you replace text in a textual region. You can overwrite text with a text string, a text segment, or a text block.

The overwrite statement replaces text with the specified string, text segment, or text block. The replacement begins at the current position of the text cursor, and each character is replaced in succession.

If an overwrite statement is executed at a location where there is no text, ESL will insert the necessary blanks prior to the text cursor, as it does with the insert statement.
