Once glyphs have been selected and connected together in a flow graph,
the programs they represent may be executed individually by clicking
on the "run" button of each individual glyph, or the entire processing
pipeline may be executed using the master action `RUN' button.
.PP
The `RUN' action button is used to automatically execute an entire 
workspace flow graph.  
Because the flow graph may contain several different paths, the scheduler
will find a correct sequence for executing the glyphs and run them in 
that order.  
Once programs have been executed, if changes are made to the flow graph,
`RUN' will re-execute only those programs that are affected by the 
change.  Therefore, the entire flow graph does not have to be Rerun.  
.PP
The `RUN' button, during processing, will be labeled `STOP'.  While `RUN' is
executing it can be interrupted by clicking on the `RUN/STOP' button
again.  
.PP
The execution mode described above is typically referred to as 
\fIdata driven\fP.  \fBCantata\fP is designed to support a more interactive
execution mode referred to as \fIresponsive execution\fP mode.  This mode
can be set on the `Workspace Attributes' pane.  If this mode is set, the `RUN'
button operation is different, please see the help for 
responsive execution mode.
.PP
The `RESET' button is used to "touch" all glyphs in the workspace so
that RUN will re-execute ALL glyphs, whether they have been modified
or not.  To just reinitialize loops, the `RESET' button on the individual
loop control glyphs may be selected.
