BREAK
When a breakpoint is taken (program stops running because of a
breakpoint). the
breakpoint at that line is removed. Another way
to remove
breakpoints is to use the UNBREAK command. If a
breakpoint is set
at a program line and that line is deleted, the
hrp::Ikpoint is i'.Ilso rf~moved. Breakpoints are removed from all
program lines
when a SAVE command or a NEW command is
entered, N
ate that in the example the breakpoint at 11 0 was
removed when the hreakpoint was taken. while the breakpoint at
130 was removed by the UNBREAK command.
Whenever a breakpoint is
taken, the standard character set is
restored. Thus. any standard characters that had been redefined
by CALL CHAR will be converted back to the standard
characters Characters defined in the range 12H·159 are
unaffected. Note that when this example program is run. a solid
bar appears on the screen until the breakpoint is taken, When
the breakpoint is
taken, the bar becomes a row of asterisks (*)
since character 42 is a standard character.
