Turn the code from 'movwf counter' through 'return' into a
subroutine.  Then load W with your desired delay value and call the
subroutine.  The sub enters with the desired delay in W which is saved into
the counter register by the first instruction of the subroutine.

If you want to have a list of pre-determined delay values that are
selected, consider using a jump table.
