S8243: COBOL/LE conversion User Experience
SHARE Technical Conference, August 26, 1999

The author will share his experiences converting 100s of COBOL II programs from a mixed COBOL (1968 standard)/Assembler environment to a pure COBOL/LE environment.

The assembler layer that performed dynamic loading and abend recovery termination services was eliminated with only minor syntactical changes to existing COBOL programs. Most assembler programs were either replaced with COBOL/LE services, or re-written in COBOL.

COBOL/LE programs developed by the author will be included in the presentation, including:

  • a compiler printer exit that reduces the volume of printed output with no loss of useful information, a program that
  • identifies 90%++ of the syntactical changes that will be required for COBOL/LE, a program that
  • adds INCLUDE CEEUOPT and SETSSI yyyymmdd to the object deck, and a program that
  • uses LE services to allocate memory and loads external files for
  • binary search table lookups.

    Compiler and LE

  • run-time options, and their effect on ability to detect errors will be discussed and recommended.

    The author has been writing COBOL programs since 1968, and is still an active COBOL programmer. He has completed COBOL II to COBOL/LE conversions for several clients. His most recent conversion effort went "live" on April 1999.
