Constraints of Native Mode
ZCOBDLL contains the COBOL utility routines which, for TNS COBOL, reside
in the system library, COBOLLIB, and CBL85UTL. ZCREDLL contains the
COBOL run-time routines which, for TNS COBOL, reside in the system library
or in CLULIB.
Constraints of Native Mode
Before you start converting applications to native mode, be aware of the constraints of
the native environment:
•
pTAL, unlike TAL, cannot contain embedded SQL statements.
•
C and COBOL programs that contain embedded SQL statements must use the
SQL release 2 feature set.
•
TNS interpreted object code, TNS accelerated object code, and native object code
cannot be mixed in one program file.
•
A program and its user library must both be native object files.
•
Mixed-language programs can consist only of C, C++, COBOL, and pTAL.
•
TNS/E native compilers and linkers are not hosted on TNS/R systems.
•
TNS/E native object files cannot be executed on TNS/R systems.
•
TNS/R native object files cannot be executed on TNS/E systems.
