Chapter 2. Setting up the software

The Readout program you have built runs an extended Tcl interpreter. Tcl is a scripting language that is

widely used throughout the NSCL as an extension language. It provides a common base language for

programming applications. Each program in turn extends this language with a set of commands that

allow you to control the application itself.

The commands we will be working with are:

begin

Begins a run. From the point of view of your code, your the Initialize and Clear member

functions of your event segment will be called. The Readout framework will respond to each trigger

by calling the Read member function of your event segment.

end

Ends a run. The readout framework stops responding to triggers.

Tell the readout program to start a run:

% begin

The >bufdump terminal session should now start spewing stuff at you. If the trigger rate is high, you may

need to stop the run to be able to read the buffers. To do this type: end to the Readout program.

When the run starts, bufdump dumps the headers of several non-event buffers. As each event buffer is

ﬁlled with data collected by the Read member function in your event segment, bufdump will dump the

buffer header and the ﬁrst event in the buffer. This might look a bit like this:

----------------------- Event (first Event) ----------------

Header:

300 1 -27712 0 1859 0 4 0 0 0 5 258 772 258 0 0

Event:
