  68. <p>It is often necessary to eliminate a breakpoint, watchpoint, or
  69. catchpoint once it has done its job and you no longer want your program
  70. to stop there. This is called <em>deleting</em> the breakpoint. A
  71. breakpoint that has been deleted no longer exists; it is forgotten.
  72. </p>
  73. <p>With the <code>clear</code> command you can delete breakpoints according to
  74. where they are in your program. With the <code>delete</code> command you can
  75. delete individual breakpoints, watchpoints, or catchpoints by specifying
  76. their breakpoint numbers.
  77. </p>
  78. <p>It is not necessary to delete a breakpoint to proceed past it. <small>GDB</small>
  79. automatically ignores breakpoints on the first instruction to be executed
  80. when you continue execution without changing the execution address.

  86. <dd><p>Delete any breakpoints at the next instruction to be executed in the
  87. selected stack frame (see <a href="Selection.html#Selection">Selecting a Frame</a>). When
  88. the innermost frame is selected, this is a good way to delete a
  89. breakpoint where your program just stopped.
