Pro-Analyzer for Delphi and Pascal is a source code analyzer and documentation generator. Pro-Analyzer allows you to generate comment headers, call diagrams, global cross references, code surveys, and other useful reports about your Delphi and Pascal programs, without needing to change your source code.Pro-Analyzer can be used for documenting and diagramming new source code, and it can also be helpful in the reverse engineering, re-engineering, or documenting of old code where the original programmers have left the project, or where no documentation exists at all. Pro-Analyzer can produce a CallMap report to documenting a program's structure. CallMap is a logic diagram of the program which shows where all the procedures and functions are called, reveals how many levels deep the sub-programs are, and shows where recursion is used.Source code can be enhanced by using the Pro-Analyzer tool. As the code is processed, any unusual conditions detected are noted on the anomaly report\; such as variables not used, variables not set, or functions that are never called. Comment headings for each sub-program can be generated, then after your inspection, can be inserted into a new copy of the source code itself. A variety of controls in the graphical user interface allow customizing the reports for specific needs. If requested, the entire output generated by Pro-Analyzer can be automatically paginated and printed as a document, complete with a title page, table of contents, headings, and page numbers. The resulting documentation can be used by computer programmers, engineers or management to understand the source program.
