Segmentation considerations
The topic lists considerations of using the SORT statement.
If a SORT statement is coded in a fixed segment, any input or output procedure referenced by that SORT statement must be either totally within a fixed segment or wholly contained in a single independent segment.
If a SORT statement is coded in an independent segment, any input or output procedure referenced by that SORT statement must be either totally within a fixed segment or wholly contained within the same independent segment as that SORT statement.
