BSL:Variables
Variables in BSL are very similar to variables in other programming languages. Here's a brief explanation of what a variable is:
When writing logical programs, one often needs the program to remember some information (a number, a piece of text, the ON/OFF state of a switch, etc) so that the information can be used at a later time.
The usual thing to do in this situation is to store the needed data in a variable: an elementary data container.
General notions
Type and value
A variable (data container) has three important attributes: the name, the type and the value.
The value or the variable is just the contents it currently stores. It can be read and written.
Also, a given variable can store only a specific type of data (floating-point number or integer or text string or boolean), and that is what we call the variable's type.
Finally, the name of a variable is a unique text string that is used to identify the data container within the script. Like function names, variable names are case-sensitive (NOTE: all variables and functions are lower-case). Valid characters are: please fill me in
An easy way to get the type and value of an existing BSL variable is to enter its name at the console in Developer Mode: you typically get console output like "bool: 1" or "int32: 42" or "float: 3.14" or "string: hello"
Declaration and assignment
If you want to use a new variable (data container), you must set it up (declare it) first, with the var keyword. A declaration statement can look a bit like this:
var int my_superduper_integer; var bool my_totally_awesome_boolean; var string my_incredible_text_string; var float my_cool_floating_point_number;
The first word is the keyword "var", next comes the type (keyword), then the name of the variable. The final ";" is required. The name can be any valid name (i.e., not a keyword and not containing invalid characters)
A declaration is usually seen at "global scope" (i.e., outside all functions). It is recommended to group declarations at the beginning of a BSL file (for readability), but it's not necessary. It is also not necessary (but strongly recommended) to declare a variable before the context where it is used for the first time.
On some occasions you may want to declare a local variable (i.e., to embed a declaration statement into a function). This feature will be detailed elsewhere.
Assignment
You can assign a new value to an existing variable with the assignment operator "=". The name of the variable you want to modify is on the left-hand-side (LHS) of the "=", and on the right-hand-side (RHS) you can have any valid expression that evaluates/converts into the variable's type.
An assignment can be combined with a declaration (see above). That means the variable will have a definite value right after it is created. If you don't specify/define such a starting value, you should not, generally speaking, assume anything about the value.
However, apparently there are "default" values assigned to every variable even if it hasn't been defined yet. Those values are 0 (i.e., false) for bool, 0 for int and float, and "" (empty string) for string.

Preset variables
- All the preset BSL variables are listed here, in alphabetical order.
- Please fill in with ssg's stuff (descriptions + OK if variable works).
- Type and default value (from console) if you're motivated enough.
- Color
- White : available on all versions
- Gray : available only on PC retail, Intel Mac and Mac beta 4
- Red : Mac beta 4 exclusive
- Green : PC retail exclusive
- Default value
- # !!! : reset by engine at level load (not checked yet for chr_buffer_size and beyond, unless specified)
- !? : set by engine at game/level load, depends on persist.dat
- Works
- "OK-I" works on Intel Mac
- "OK?" means confirmation/refinement required.
