Formatting

A bcs model, from top to bottom, consists of three sections:

• definition of static variables,
• definition of processes,
• system line (that is, the initial processes that are in the system at t=0).

In bcs, lines must be terminated by semicolons and any whitespace/newlines are ignored. If we want to define some variable x that will be used by a process, the three lines:

x = 5;
x                 = 5;
x
=
5;

are all acceptable. Variables may be assigned either a float or an int, so assigning:

x = 3.452;

is acceptable. Variable names must either lead with an underscore or a letter. Thereafter, they can contain letters and numbers. However, leading with a number is not allowed. The following variable names are valid:

myVar
_myVar
__myVar
m1yVar99

But a variable name such as 99myVar is not.

Comments are specified by // which tell the bcs parser that the rest of the line should be ignored.
