ABC is an interactive programming language and environment for personal computing. It was originally intended as a good replacement for BASIC and was designed by first carrying out a task analysis of the programming task.
dfd files contain dyadic functions for ABC. In ABC terminology, dyadic functions operate on two operands. The files provide function data used by the language environment.
Open an dfd file with a compatible ABC programming language environment. These files are normally used by ABC itself, so they may not open meaningfully as standalone documents.
If ABC is not installed, a general text or binary editor may show the file contents, but it will not interpret the dyadic functions or provide a usable view of the data.
