Enables the delivery of asynchronous system traps (ASTs) in your
    program.

    Format

      ENABLE AST

1  –  Description

    The ENABLE AST command enables the delivery of ASTs while your
    program is running, including any pending ASTs (ASTs waiting
    to be delivered). If ASTs are delivered while the debugger is
    running (processing commands, and so on), they are queued and are
    delivered when control is returned to the program. Delivery of
    ASTs in your program is initially enabled by default.

                                   NOTE

       Any call by your program to the $SETAST system service that
       disables ASTs overrides a previous ENABLE AST command.

2  –  Example

  DBG> ENABLE AST
  DBG> SHOW AST
  ASTs are enabled
  DBG>

      The ENABLE AST command enables the delivery of ASTs in your
      program, as confirmed with the SHOW AST command.
