break

	Format 1: `break`
	Format 2: `break` HOOK-TYPE [when (EXPRESSION)] 1 [`count` n]

Format 1: The break command is used without arguments only within an on command because you specify the location of breakpoints as part of the on command syntax.

Format 2: See Using Debugger Commands for the details of the HOOK-TYPE argument, which is used to specify line-number hooks as breakpoints.

Identical requests: If a break request is made that is identical to an existing one, the identical request is not installed. This is true whether the request to be installed is within an on command or typed in at the command line.

break *: breaks at every line-number hook in a source file compiled with debug .
break entry: breaks on entry to all functions.
break calls: breaks at each call to a function and at each return from a function. (In the case of function calls, program execution is interrupted twice for each function called: on calls from functions and on return to the calling function.)
break main 45 count 10: breaks at line 45 of the main function the tenth time the line-number hook at that line is reached. After that, it breaks every time line 45 is reached.
break 53: breaks at line 53 of the current function.
break (comp23) entry: breaks on entry to any of the functions in the comp23 section.
break func1 entry when (parm1 ==5): breaks on entry to the func1 function when the value of parm1 is 5.
