PL/I considerations

PL/I programs written to the external CICS® interface must provide their parameters on the CALL to DFHXCIS in the form of an assembler-style parameter list.

The EXCI copybook for PL/I, DFHXCPLL, contains the necessary definition of the DFHXCIS entry point, as follows:

 DCL DFHXCIS  ENTRY         OPTIONS(INTER ASSEMBLER);

The same rule applies for the EXCI LINK command, and in this case the CICS translator ensures that the correct parameter list is built.

For an example of an EXCI client program written in PL/I, see the source of the sample program, DFH$PXCC.
