Technical Support

Describe the problem briefly.
Submit the smallest possible code snippet in the original source code language which allows us to reproduce the problem.
Submissions must include a description of the problem and a code sample to demonstrate the problem.
No links please. If you can't demonstrate the problem in a small code snippet, send us a small zip file with just the files necessary to reproduce the problem.
Some issues are not resolvable and some code may need to be rewritten rather than converted.
Some adjustments are always necessary to obtain compilable code. Code converters are designed to merely reduce the amount of work required.
Support is limited to issues that involve improving the converter. Support does not include assistance in making the adjustments necessary to obtain compilable code.
Send submissions to support.
