2.1 The FLL Foundation


At its core, XFRX relies on a compiled FoxPro Link Library (FLL). This binary file contains the low-level logic required to process the binary FRX report definition files and translate drawing commands (lines, shapes, text) into file structures specific to the target format (e.g., the object stream of a PDF). This ensures high performance and low memory overhead during the generation process. xfrx documentation
