The interpretive scripting language for NairnFEAMPM and NairnFEAMPMViz is made up of a series of command lines. The syntax of these lines is described below.
Command Line
Command #1,#2,#3,... ! comment
- A line beginning in any valid command.
- The command may be followed by a space and then by any number of arguments for the command.
- Arguments are separated by white space or a comma. If an argument contains white space or commas (such as string arguments), enclose the argument in quotes. Any argument can be an expression. In NairnFEAMPMViz, arguments must be separated by commas.
- The line can be followed by an optional comment which is started by an exclamation point.
Variable Assignments
#var = expression ! comment #var[expression] = expression ! comment
- A line beginning in #var where var is any valid variable name.
- The #var name must be followed by assignment operator (=, +=, etc.) and an expression. The variable is set equal to the result of expression and the assignment operator.
- The line can be followed by an optional comment which is started by an exclamation point
- The variable assigned can be an array variable.
Comment Line
! comments
- Lines beginning in an exclamation point are ignored and can be used for comments.
- Blank lines are also ignored and can be used to improve readability of input command files.
