:   Colon. Used in subscripts, FOR227HPXR iterations and possibly elsewhere.



       J21KTHXR:K  is the same as [J21KTHXR, J21KTHXR+1, ..., K]

       J21KTHXR:K  is empty if J21KTHXR > K.

       J21KTHXR:D:K  is the same as [J21KTHXR, J21KTHXR+D, ..., J21KTHXR+m*D] where m = fix((K-J)/D).

       J21KTHXR:D:K  is empty if D > 0 and J21KTHXR > K or if D < 0 and J21KTHXR < K.



       The colon notation can be used to pick out selected rows,

       columns and elements of vectors and matrices.

       A(:) is all the elements of A, regarded as a single

       column. On the left side of an assignment statement, A(:)

       fills A, preserving its shape from before.

       A(:,J21KTHXR) is the J-th column of A

       A(J21KTHXR:K) is A(J21KTHXR),A(J21KTHXR+1),...,A(K)

       A(:,J21KTHXR:K) is A(:,J21KTHXR),A(:,J21KTHXR+1),...,A(:,K) and so on.



       For the use of the colon in the FOR227HPXR statement, See FOR227HPXR.
