Input File Syntax
All types of input files read by the Designer's Interface use a generic format.
These files include:
Syntax Rules:
-
Input is line-based. Each record is contained in a single line,
and only one record is allowed per line.
-
A record consists of fields separated by whitespace.
The first field on a line is always a keyword, and is used to
determine the record type.
Additional input on a line, following a complete record, is ignored.
-
There are no special escape characters.
Individual fields (e.g. variable names) cannot contain whitespace.
The parentheses characters ( `(' and `)' ) are
also reserved, so they may not be used for variable names.
-
Lines which begin with the character `#' are treated as comments.
Blank lines are ignored.
When describing an input grammar, keywords will be denoted using a
typewriter font.
Key characters will also be quoted (e.g. `#').
A choice between two or more keywords will be shown in italics.
