Linkage section
The linkage section describes data made available from another program or method.
Record description entries and data item description entries in the linkage section provide names and descriptions, but storage within the program or method is not reserved because the data area exists elsewhere.
Any data description clause can be used to describe items in the linkage section with the following exceptions:
v You cannot specify the VALUE clause for items other than level-88 items.
v You cannot specify the EXTERNAL clause.
You can specify the GLOBAL clause in the linkage section. The GLOBAL clause has no effect for methods, however.
