BREAK
Syntax
BREAK <address> [<n>]
Descri~tion
The BREAK command sets a breakpoint at a given even address
after clearing any previously set breakpoint. If <n> is
given, program execution is not interrupted until the nth
time the breakpoint instruction is encountered «n> is in
the range %l-%FFFF). If <n> is not given, 1 is assumed. If
the BREAK command is issued with no parameters, any previ-
ously set breakpoint is cleared. When program execution is
suspended by the BREAK command, the Monitor Program displays
a message reporting the break and the address where it
occurred.
