Input File Syntax Sample Clauses

Input File Syntax. The previous section described many of the basics required for an input le. This section gives a more complete and detailed description of the input le format and should serve as a reference. Some general facts about le syntax: Lines are processed sequentially. Uppercase is converted to lower case. \*" at the beginning of a line marks a comment line. Lines are restricted to 1000 characters but can be continued with a \+" as the rst character of subsequent lines. Intervening \*" lines are allowed in this release. The rst line in the le is considered the title line and is ignored. It is recommended that this line start with an \*" for future compatibility and le concatenation. The le must end with the .End keyword. Names of objects are limited to 80 characters. In general, each line of the input le will either de ne some geometrical object, such as a node or segment, or it will specify some program parameter. All input lines that de ne geometrical objects begin with a letter de ning their type, and then some unique alphanumeric string of up to 80 characters. For instance, all node de nitions begin with the letter N. This sets object lines apart from parameter speci cation lines which begin with a period, \.". The remainder of this section will describe all possible input lines. In the following description, any argument enclosed in `[ ]' indicates an optional argument. If not included on the input line, the actual value used for this argument will be either the program default, or the user default de xxx by the .Default keyword (described below).
