Use of HIGH and LOW for pin outputs

[rnuke77]

Sorry, I didnt know how to use the Code: boxes but here is the "non-working" code:

 
DEFINE OSC 4 'Define for 4MHz crystal
DEFINE LOADER_USED 1 ' Boot loader for ICSP
'
' ***** Configure I/O ************************************************
PORTC = %00000000
TRISC = %00000000
Rel1 var PORTC.0 ' Relay1 Transistor input
Rel2 var PORTC.1 ' Relay2 Transistor input
Rel3 var PORTC.2 ' Relay3 Transistor input
Rel4 var PORTC.3 ' Relay4 Transistor input
'
Startup:
