Thank you Acetronics, thanks to you, I now understand everything I need to understand for my Build from scratch Tricorder Project.
This is the note I have compiled based on what you have explained.
'Make them all outputs, Remember Pin 4, PortA.5 will always be Input Only
'And Pin 3, PortA.4 needs a pull up resistor.
'Understand that these two lines will make High, all Pins
'meaning the LEDs will ALL light up.
TRISA = 0 'Set all PortA Pins as Outputs
TRISB = 0 'Set all PortB Pins as Outputs
'Make All PortA and PortB's lights Down, the "&" here means "Clear".
PORTA = PORTA & %00000000
PORTB = PORTB & %00000000
Make PortA and PortB's .0 lights up, the "|" here means "Set".
PORTA = PORTA | %00000001
PORTB = PORTB | %00000001
[This is a powerful concept Bracer, with this you no longer need to do the:
High PortB.0 crap.
A single line to clear all and a single line to set all, the ONLY THING YOU MUST
take note is to line up your LEDs from PortB.7 to PortB.0 in your device instead
of 0 to 7, this is because as you can see, this one line code is backward, setting
the last digit to 1 actually set Port*.0 and %10000000 sets Port*.7 to high.
So to make it easier for you to visualize your
lights animations [I'm repeating myself here], set your LEDs on your device from
Port*.7 [Or whatever is the highest port number you use for output] to lowest.
]
[This also means that setting:
PORTA = PORTA | %00100000
is useless because PortA.5 [Pin 4] can only be use for input detection,
setting it to high means nothing.

It's still very much in WIP but I will be sure to give you credit when I've come to the electronic part of the Tricorder.
