Transformation of computer programs and eliminating errors

A method and system for transforming a first computer program having program statements to a second computer program. A parsed first computer program is translated to the second computer program. The first computer program includes a first program statement that includes a first error. The translating includes: (i) identifying a second program statement in the parsed first computer program that includes a second error and has thrown a translation exception with respect to the second error, (ii) rolling back the translating to a predefined check point prior to the second program statement in the parsed first computer program such that the predefined check point is associated with a statement in the parsed first computer program that was successfully translated, and (iii) generating an executable equivalent translation for the second statement. After the translating, a mapping of one or more statements is generated.
