This report is in two major sections. The first presents a High-Level Grammer Specification Language HGSL which greatly simplifies the development of a complex augmented transition network grammar ATN. A compiler converts HGSL expressions into a transition network which a simple interpreter uses for parsing. The algorithms used by the compiler and interpreter are presented. The second section presents the HGSL for a large grammar for technical prose. The grammar was developed to allow parsing of technical training materials in the draft stage of writing, as part of a computer-based comprehensible writing aid. Some results on the coverage of the grammar are presented to show that the grammer is close to being practically useful.
