Preprocessing of typed two-dimensional mathematical expressions
TLDR
An algorithm is discussed which translates two-dimensional mathematical expressions such as subscripting and displayed division into a string form suitable for input to a classical compiler.Abstract:
An algorithm is discussed which translates two-dimensional mathematical expressions such as subscripting and displayed division, that have been prepared using a keyboard input device, into a string form suitable for input to a classical compiler. The algorithm allows reasonably general forms, yet is sufficiently simple to be practically applicable today. It may be used as a preprocessor to an existing compiler in order to improve the readability of an existing language.read more

A potpourri of notational pet peeves (and their resolution in modcap)
TL;DR: This paper discusses some of the author's pet peeves regarding common language notations and describes how the Modcap language avoids them and has four sections -character sets, identifiers, page formatting, and expressions -followed by a brief conclusion.

Syntax-Directed Recognition of Hand-Printed Two-Dimensional Mathematics
TL;DR: In this article, a set of replacement rules are used to parse two-dimensional configurations of characters, similar to the Backus Normal Form rules used to describe a class of syntaxes for character strings.

A method for the structural analysis of two-dimensional mathematical expressions
TL;DR: Algorithms are developed to test whether a pattern has a (strongly) well-formed structure with respect to a given structure specification scheme, which is applicable to the analysis of two-dimensional mathematical expressions and the format of printed material.
