element

So this is a simpler form of my problem. Lets say I have 2 arrays. A= {1,2} and B={2,4,6}. If A and B share an element then delete that element from B. I know you can loop through and compare each element in A to each element in B, but there's got to be a better way!

RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
