program property GenCobStaticArrays for preventing Cobol runtime overhead for dynamic arrays

Dear Sir or Madam,
we from PKS Company are developing as partner of IBM tools for migration from RPG/Cobol to EGL. Thereby we encounter heavy performance problems, because all the originally static arrays will become dynamic arrays with huge runtime overhead when generating to Cobol.

So we suggest to include a property like GenCobStaticArrays, that could be specified at program level or at build descriptor level, where all Arrays will be generated as static arrays like it allready is true for structure field arrays. The performace of structure field arrays is much better when generating to Cobol and this is our workaround for now. But embedding a standalone array within a record just to get it static is not the best way of converting programs to EGL.
kind regards
Andreas Gronert

    This RFE is being rejected as another method was used to reduce overhead of using dynamic arrays. The alternate method was a rewrite of the dynamic array handling which was shipped via the PTF UK92032 for the Rational COBOL Runtime for zSeries product.

    We agree that this would help peformance, and it is consistent with other improvements we are investigating to imrprove both COBOL and Java runtime performance.

    This enhancement will be considered in our planning for future releases, but we do not currently have a time frame for delivery.
