Delete line in list {line-number (calculation)}


This command deletes the specified line of the current list by moving all the lines below the specified line up one line. If the line number is not specified or if it evaluates to 0, the current line LIST.$line is deleted. The line in a list selected by the user can determine the value of LIST.$line and is the line deleted if no parameters are specified. LIST.$line is unchanged by the command unless it was the final line and that line is deleted; in this case LIST.$line is set to the new final line number. The command never releases any of the memory used by the list.

The flag is cleared if the list is empty or if the line is beyond the current end of the list; otherwise, the flag is set.
