Although the source code was usually stored in a tokenized version to save room on disk, pieces of code could also be saved in ASCII form, and as such made it possible to set up reusable libraries. The tokenized source files were a benefit in other ways too — for instance, GFA BASIC allowed users to include binary data in their BASIC code via an "INLINE" statement, and could even be integrated with the GFA Assembler to allow users to develop machine code programs inside INLINE statements in order to accelerate particular areas of a program. It also meant that the BASIC interpreter (and later the compiler) didn't need to tokenise a program when it was loaded, which would have been a significant load-time overhead for some of the larger GFA BASIC programs that were written.
