PIC BASIC grammar

I assume you mean command set.

Not really but this very helpful also. Im searching for a grammar file which describes the language which can be input for compiler generator programs like yacc. Is pic basic a subset of a real basic language (for example visual basic)?

Thanks

Talking yacc, I assume you are wanting to compile it for Unix, if so, I can't help there.

However pic basic was first done with interpreted basic by Parallax, and closely followed by a compiler from Melabs.

There are many other variants now, but I would suggest Melabs is the most commonly used basic compiler today.

You will find the basic commands evolved out of a need to control PIC I/O and registers. Things such as PIN1 HIGH won't be found in any former basic, and many liberties are taken to produce Pic Basic.

Neither PIC nor Visual Basic are standardized languages - they vary on the whim of their creators. The input language for Yacc is fully described in the documentation of yacc (or bison).
