Save areas

Any non-XPLINK assembler routine used within the scope of a Language Environment application must use standard S/370 save area conventions. Any XPLINK assembler routine used within the scope of a Language Environment application must use XPLINK save area conventions.

Note:
  1. To call a COBOL program from assembler, set the first two bytes of the save area to hex zero.
  2. Language Environment does not support the linkage stack.
  3. A non-Language Environment-conforming assembler routine must have its own save area.
