Here is a super simple example called SIMPLE.BPP.Īn animated GIF demonstrates the process of using the program. The tokenized form is written to the output PRG file. In order for BPP.PRG to create tokenized BASIC programs, it has a small machine language routine in golden RAM that converts from plain text to tokenized form. Normally as you enter lines of BASIC the computer will translate them into a compressed tokenized form, and this is necessary for the programs to be usable. The one exception has to do with tokenization. The program is written almost completely in BASIC. The preprocessor (probably) requires an emulator built from the master github branch. Much as strings begin and end with a quotation mark ("), macro constructs begin and end with a commercial at sign This means that you cannot include in a macro, but otherwise any character may be used.Ī label can be defined on a line by itself as label can be referenced after a GOTO or GOSUB as (including ON statements).Ī long variable name can be used as preprocessed comment can be used as whatever text you want These comments are not written to the PRG file.Īny leading whitespace on a line is removed before writing the code to the PRG file. BASIC PREPROCESSOR allows one to create Commodore BASIC programs with a normal text editor without line numbers.
