Physical Terminals
The syntax "J1 : 1" means pin 1 on connector J1 - this is what we call a physical terminal. This feature means that connector pins can be placed all over a design. This aids neatness and clarity and avoids the need to run wiresacross the diagram to reach a single connector component.

VCC VDD
Merging Nets
This is perfectly acceptable in ISIS.
It means that all VCC dan VDD pins will be connected together.
It is also possible to have different groups of VCC pins connected to different nets if this is required.

Wires And Multiple Wire Labels
As well as allowing you control over the potition and appearance of individual wires and their label(s) ISIS also allows you any number of labels per wire.

STB J1:6
Logical Terminals
Here we have logical terminals which make a connection without using a wire-the two STB terminals are deemed to be connected.
Such connections can be made across sheets too.
Note also how a proper inversion bar can be used. The label is entered with a dollar ($) symbol before and after the part of the text to be over-barred. In this case the text is $STB$.

Multi-Element Homogeneous Parts
Here we see how ISIS support multi-element parts where all parts are basically identical-hence the term 'homoneneous'.
The syntax "U1:B" means "element" B of U1. Once a part has a reference like this, its pin numbers change automatically according to the element specified.

Routing Strategies
The above wire labels convery strategy informations to ARES.
Net names VCC and GND take POWER strategy automatically.
Alternatively, you can define a default strategy for all wires on a sheet using a *NETPROP script objects such as the one shown below.

Multi-Element Heterogeneous Parts
Here we see a Heterogeneous Multi-Element Device. Unlike the homogeneous example on the left here the parts of the overall device (a relay with a single coil and two SPDT contacts) are different.
In other words, the relay coil and the two contacts all belong to a the same physical component but can be placed separately on the schematic.
