APAR status

  • Closed as program error.

Error description

  • Rational Business Developer V7.1.0.1:

The result with generated COBOL programs are incorrect when a
statement does multiple calculations.  For example, the result
of the following EGL statement in the EGL debugger is 85 which
is correct, while the result with the generated COBOL is 33.

    wy4fn97.chk_Dgt = (wy4fn97.acc_Nr * 100) % 97;

Local fix

  • The workaroud is to define and use a temporary EGL variable that
is large enough to hold the intermediate results.

Problem summary

  • Incorrect results were due to the intermediate types for
binary experssions not being computed well enough

Problem conclusion

  • A new algorithm has been implemented that mirrors one used
by Cobol compiler.

Temporary fix
