We characterize solutions to the problem of minimizing a convex integr
al objective function subject to a finite number of linear constraints
and requiring that the feasible functions lie in a strip [alpha,beta]
where alpha and beta are extended real valued measurable functions. W
e use the duality theory of J. M. Borwein and A. S. Lewis (Math. Progr
amming, Series B 57 (1992), 15-48, 49-84) to show that the solutions a
re of the usual form, but truncated where they leave the strip. (C) 19
