maintain the modularity and readability of large programs, Data Explorer provides
two tools that allow connections between input and output tabs of
separate modules without the use of a visible connecting line. These
tools, Transmitter and Receiver, allow you to separate visual programs into
logical blocks. For example, the output of several logical blocks can
be transmitted to another block that receives them, collects them, and
produces an image. #!N #!N Receivers and Transmitters can also be
used to communicate information between pages in the Visual Program Editor
(see #!Lvpepage,dxall356 h Creating pages in the VPE #!EL in IBM Visualization Data Explorer User's Guide). Pages are
a valuable way of structuring complex visual programs into logical blocks.
Note: Macros provide another way of structuring visual programs in logical
blocks (see #!Lmacros,dxall435 h Creating and Using Macros #!EL in IBM Visualization Data Explorer User's Guide). #!N
#!N To remotely connect input and output tabs: #!N #!I0 #!N
#!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1. Select a Transmitter tool (in
the Special category in the tool palette) and place it near
the output tab of the module that is to be "connected."
#!N #!I30 #!N 2. Connect the module's output tab to the
Transmitter's input tab. #!N #!I30 #!N 3. Select a Receiver tool
(also in the Special category), and place it near the input
tab of the other module that is to be "connected." #!N
#!I30 #!N 4. Connect the Receiver's output tab to the second
module's input tab. #!N #!N The Transmitter and Receiver are now
connected. #!N #!I0 #!N #!EF #!N #!N #!N The Receiver automatically
assumes the same name as the Transmitter. More than one Receiver
can be connected to a single Transmitter and they assume the
same name until a new Transmitter is placed on the VPE
canvas. #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. To
change the name of a Transmitter and Receiver, use the #!F-adobe-times-bold-r-normal--18*
Notation #!EF field of the appropriate configuration dialog box (see #!Lucb,dxall345 h Entering Values in a Configuration Dialog Box #!EL
in IBM Visualization Data Explorer User's Guide). Changing the name of
a Transmitter changes the name of all the Receivers connected to
it. Changing the name of a Receiver affects only that receiver.
