I have the following code:
Parse var onepage 1 oneline 81 rest

If I want '1' and '81' to be variables, I can use one of the followings:
1. Interpret 'Parse var onepage' x 'oneline' y 'rest'
2. oneline="SUBSTR"(onepage,x,y-x); rest="SUBSTR"(onepage,y)

My questions are:
1. which is more efficient: 1st method or 2nd method?
2. is there a better (more efficient) method?
