Document Summary

You can use the command: break . You can obtain the line numbers from the listings file (. l). You can clear a breakpoint by using the delete . Note: don"t set a breakpoint at the first executed instruction of your program.

Using breakpoints info breakpoints break linenumber operation exit gdb print description of debugger command cmd. Without cmd prints a list of topics. runs the program. Print a list of all breakpoints and their numbers (the numbers are used for other breakpoint commands) set a breakpoint at line number linenumber. See the listing file (prog. l ) for line numbers. continue list kill delete [bpnum1] [bpnum2] clear linenum. Stepping through the program next i (or just n) stepi (or just i) finish.
