|

|

1. Write ``Math.gf``, which defines what you want to say.

```
|

abstract Math = {
|

abstract Math = {
|

||||

||||
}
|
||||
}
|
||||
```
|
||||
2. Write ``Lex.gf``, which defines which language-dependent
|
||||
parts are needed in the concrete syntax. These are mostly
|
||||
words (lexicon), but can in fact be any operations. The definitions
|
||||
only use resource abstract syntax, which is opened.

```

|
||||
}
|
||||
```
|
||||
3. Write ``LexEng.gf``, the English implementation of ``Lex.gf``
|
||||
This module uses English resource libraries.
|
||||
```
|
||||
instance LexEng of Lex = open GrammarEng, ParadigmsEng in {

||||
zero_PN = regPN "zero" ;
|
||||
|
||||
}
|
||||
}
|
||||
```
|
||||
4. Write ``MathI.gf``, a language-independent concrete syntax of
|
||||
``Math.gf``. It opens interfaces can resource abstract syntaxes,
|
||||
``Math.gf``. It opens interfaces.
|
||||
which makes it an incomplete module, aka. parametrized module, aka.
|
||||
functor.

5. Write ``MathEng.gf``, which is just an instatiation of ``MathI.gf``,
|
||||
replacing the interfaces by their English instances. This is the module
|
||||
that will be used as a top module in GF, so it contains a path to

the libraries.
