BREAK
The BREAK command may also be used as a statement in
programs. If the BREAK command is entered as a statement with a
line-Jist, then breakpoints are set at the line numbers specified.
Breakpoints set in this manner may be removed as discussed
earlier.
Remember. though, when the BREAK command is entered
as a statement with a line-list, the breakpoints are set agaIn each
time the statement is performed.
If the BREAK command is entered as a statement and no line-list is
specified,
then the statement itself acts like a breakpoint. Each
time the statement is performed. the program stops running. The
only way to keep the program from stopping at a BREAK
statement is to delete the line from the program, Note that a
BREAK command without a line-Jist may only be entered as a
program line.
If you specify a lin~ num her in the line-fist which is equal to zero or
greater than 32767, the message "BAD LINE NUMBER" is
displayed
and the command is ignored (no breakpoints are set at
any line spf'rifieci)
If you specify a line number in the line-jist which is a valid line
number but is not a line in the program, the warning "BAD LINE
NUMBER' is displayed. Breakpoints will be set at the lines
specified which are program lines.
