Index ranges

Index ranges are not allowed on scalars, matrices or tensors, but subsets of vectors or string variables may be eliminated by including an index range. For example:

DESTROY X[5:25:5] Y[IDX] S[1:5] T[2][1:10]

will eliminate elements 5, 10, 15, and 25 from vector X. If IDX is a vector, then Y[IDX[1]], Y[IDX[2]], … Y[IDX[#]] will be eliminated. If S is a string variable, characters 1 through 5 will be eliminated. If T is a string array variable, then characters 2 through 10 of string 2 will be eliminated.
