# MATH(JOSS)

WIP Reimplementation of MATH(JOSS) in typescript.

This is IBM's version of the JOSS language, written for

the System/360. It's also referred to as MATH or MATH/360.

It's probably very similar to normal JOSS, but I'm using

the IBM reference manual, so...

Currently, only some basic constructs are implemented

(expression evaluation, Type/Set/Do/if/for/times).

`tests/` roughly tracks what should currently work.

At the moment, it's not as restrictive as the original:

- slightly more helpful errors

- allows multi-char identifiers

- more relaxed about spaces in expressions

- no 10 dimension/10 argument limit on arrays

- javascript floats (i.e. greater range/precision)

But, error handling also needs work (e.g. type safety

rather than casting everywhere and hoping for the best).
