Language Environment supports the PLITDLI, ASMTDLI, and EXEC DLI interfaces from a PL/I routine. It also supports CEETDLI interface from a Enterprise PL/I routine running under IMS/ESA® Version 4.
Under Language Environment, CEETDLI is the recommended interface. CEETDLI supports calls that use an Application Interface Block (AIB) or a Program Communication Block (PCB). For more information about AIB and a complete description of the CEETDLI interface, see IMS/ESA Version 4 Application Programming Guide.
