DFSLLCLC

DFSLLCLC (in source module DFSLLCL0) is a CSECT within the DL/I space management load module DFSDHDS0. It decides what the limits will be in the next search for free space.

IMS has a multiple step algorithm for deciding where to search next for free space and for what the upper and lower ranges are around the chosen starting point. (Please see the description for CSECT DFSGGSPC for a discussion of this algorithm). This CSECT implements that algorithm.
