PK85385: Rational Business Developer V7.1.0: Size of generated COBOL programs larger than with V6 support

APAR status

• Closed as program error.

Error description

• Rational Business Developer V7.1.0.2:
  
  The size of V7 generated COBOL programs is larger than the
  programs generated with the V6 support.
  
  The following are reasons for the larger COBOL program size:
  
  - The architecture of the generated programs was extensively
    revised in Version 7 to support the complete Enterprise
    Generation Language (EGL) syntax including string data types.
    In addition to supporting strings in V7, exception handling is
    supported.  Both of these causes more code to be generated.
  
  - There is significant logic for the managing of program and
    library memory.
  
  - Due to performance reasons, most of the runtime library
    functions are now in-line in the COBOL instead of calling the
    runtime.  This produces more code but this code runs much
    faster.
  
  Even though the size of the generated COBOL programs contain
  more lines, in most cases, the V7 generated COBOL programs run
  faster than the V6 programs.
  

Local fix

Problem summary

• Added topic to migration section of information center
  describing the increase of code generated for COBOL when
  migrating to V7.
  

Problem conclusion

• Documenation update.
  

Temporary fix
