If an incorrect character is entered as a line is being
typed, it can be deleted with the DElete key 'or with
BAC<SPACE •
DElete surrounds the deleted character (s) with
backslashes, and
~PACE'
has the effect of backspacing
over a character and erasing it. Once a character(s) has
been deleted, simply continue typing the line as desired.
To delete.a line that is in the process of being typed, type
Control-U.
A carriage return is executed automatically
after the line is deleted.
To correct program lines for a program that is currently in
memory, simply retype the line using the same line number.
BASIC-SO will automatically replace the old line with the
new line.
More sophisticated editing capabilities are provided in the
Extended and Disk versions of BASIC-SO. See EDIT, Section
2.16.
To delete the entire program that is currently residing in
memory, enter the NEW command. (See Section 2.41.) NEW is
usually used to clear memory prior to entering a new
program.
If BASIC-SO de~ects an error that causes program execution
to terminate, an error message is printed. In the SK
version, only the error code is printed. In the Extended
and Disk versions, the entire error message is printed. For
a complete list of BASIC-SO error codes and error messages,
see Appendix
