Systems and methods for generating segment-specific source code for mainframe-source artifact

A system comprising:

• a processor;
• and
• non-transitory computer-readable storage medium comprising program instructions stored thereon that are executable by the processor to cause the following operations for generating segment code for a legacy mainframe-source artifact:
• receiving, from a compiler, a compiler-analysis artifact (CAA) generated by compiling a mainframe-source artifact (MSA);
• generating, from the CAA, an abstract-syntax-tree (CAA-AST);
• identifying, based on the CAA-AST, a plurality of logical segments of the MSA;
• for each logical segment:
• determining a segment descriptor comprising a segment identifier and a segment label;
• generating a segment-code prompt based on the segment descriptor;
• and
• generating, by applying the segment-code prompt to a large-language model (LLM), segment code;
• and
• integrating the segment code of the plurality of logical segments to form integrated project code for the MSA.
