Section Six - Applications Monitor
The applications monitor is a memory resident program which is useful
in debugging sequences of GPIB calls from within your application.
The monitor provides the capability to trap on return from GPIB driver
calls, allowing you to inspect function arguments, buffers, return values,
GPIB global variables, and other pertinent data. You may select the
trap so that it occurs on return from every GPIB handler call, returns
only on those calls which return an error indication; or occurs only on
those calls which are returned with particular bit patterns in the GPIB
status word.
While trapped, you will see a popup screen (Figure 6.1) that provides
details of the call being trapped. In addition, you can view a listing of
up to 255 of the preceding calls to verify that the sequence of calls and
their arguments have occurred as intended.
