Using LE Services in z/OS

Why take this course?

After completing this course, you will be able to
  • Code programs using one or more of the LE-conforming compilers:
    • IBM Enterprise COBOL for z/OS and OS/390, COBOL for OS/390 & VM
    • z/OS C/C++, XL C/C++
    • IBM Enterprise PL/I for z/OS, PL/I for MVS & VM, Visual Age PL/I for OS/390
    • or Assembler language
  • Include FORTRAN programs in the mix, even though none of the current FORTRAN compilers are LE-conforming
  • Invoke LE message management services to create and issue user run time messages
  • Use LE storage management services for holding large tables or entire files in virtual storage
  • Use LE condition handling routines to intercept and handle appropriate conditions under user control
  • Use LE date and time services for working with dates, times, and durations.

Assembler programmers may explore using preintialization services and Library Routine Retention services
Note: z/OS V1R6 and later support 64-bit LE-conforming applications in C/C++ and Assembler. LE callable services are not supported. There are some new runtime options to support AMODE 64. 64-bit issues are not discussed in this course, but are covered in a separate course. Students who complete this course will be able to use the major facilities of the product "Language Environment for z/OS", and will be able to describe the benefits and tradeoffs involved in using LE under z/OS.
Audience
Experienced programmers who will be designing and coding applications that are to be run in a z/OS environment.
Prerequisites
At the very least, the student entering this course should have a strong programming background in at least one of: COBOL, PL/I, C, or Assembler.

Major topics covered

  • Run-time environments
  • LE message services
  • The CEEBLDTX exec
  • Tokens, return codes, and termination
  • Storage management services
  • Dump and abend services
  • Condition handling services
  • Inter Language Communication
  • Assembler concerns
  • Preinitialization services (PIPI)
  • Library Routine Retention (LRR)
  • Date and time services
  • LE Math services
  • LE international services and locales
  • LE CICS, IMS, and nested enclave concerns
  • XPLINK considerations
