Specifying inputs: arcs and icons #!N #!EC #!N #!N A visual
program is a "network" of interconnected tool modules. In the VPE
window, this network is represented as a set of tool icons
connected to one another by lines ("arcs") representing the data (
#!Lvpwndw4,dxall6 f Figure 4 #!EL in Tutorial I shows such a network.) #!N #!I0 #!N

#!N #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1. Position
the cursor on an output tab of an icon and hold
down the left mouse button: the cursor becomes a downward-pointing arrow,
and a parameter or data name for that tab appears on
the icon. #!N #!I30 #!N 2. Drag the cursor to another
icon: the output tab remains connected to the cursor by a
highlighted line (arc). If the connection is valid, the input tab(s)
will be highlighted when the cursor arrow touches the icon. (If
the connection is invalid, the tab(s) will not be highlighted, and
an error message will appear. #!N #!I30 #!N 3. Release the
mouse button to establish a connection to a valid input tab.
#!N #!N #!I0 #!N Notes: #!N #!I30 #!N a. If the
"receiving" icon has two or more valid input tabs, if you
release the mouse button when the cursor is on the main
part of the icon, the connection to the first (leftmost) tab
is automatic. To establish a connection to a different tab requires
placing the cursor on that tab before releasing the mouse button.
#!N #!I30 #!N b. You can establish a connection starting with
an input tab and dragging the arc to an output tab.
