Yes and no, you can use our old friend Skimask's favourite character - the colon - and do
Code:
High GPIO.0 : High GPIO.1 : High GPIO.2
But it doesn't make any difference as to how it actually works, it will generate exactly the same code when compiled as having each command on a separate line.

What you usually do is write directly to the register, or port in this case, like this:
Code:
TRISIO = %11100000 'Set lower five bits to outputs
GPIO = %00000111   'Set the lower three bits.
PAUSE 1000
GPIO = %00010101   'Set some other bits.
The HIGH and LOW commands automatically sets the pin to an output (by also writing to the TRIS register "behind the scenes" (basically what the OUTPUT command does)) which is handy sometimes but completely unneccessary to do EVERY time you change the state of the pin. By using the more "direct" aproach you'll save code space and execution time.
