Assembly language program converter

A computer-implemented method for converting an assembly language computer program into a high-level language computer program, comprising the steps of:

• assembling the assembly language computer program with an assembler and generating an assembler listing;
• reading and storing said assembler listing in an array in memory, each line of said array being chained to its logical neighbors by forward and backward pointers;
• grouping lines of each control section in said assembler listing together;
• logically tracing said assembler listing, determining which lines are logically reachable, and accordingly marking reachable lines;
• determining an instruction type for each reachable line and accordingly identifying each line by type;
• building a data table having a hierarchy of data elements in said assembler listing;
• determining an hierarchy of sections of code caused by branch instructions in said assembler listing and accordingly labeling each section;
• building a data division from said data table;
• and
• converting lines of said assembler listing into lines of a source program in said high-level language and storing in said memory.
