// BlitzBasic Built-Ins
|
|
// - Include: Followed by a String, which is the file to include at this location.
|
|
// - Const: Defines one or more constants, which can not be modified.
|
|
// - Local: Defines one or more local variables, which can be modified.
|
|
// - Global: Defines one or more global variables, which can be modified from anywhere.
|
|
// - Dim: Defines a dynamically resizable array, globally accessible and modifyable.
|
|
// - If, Then, ElseIf, EndIf: Your classic If.
|
|
// - Select, Case, Default, End Select: Your classic Select.
|
|
// - For, To, Step, Next: Your classic For loop.
|
|
// - While, Wend: Your classic While loop.
|
|
// - Repeat, Until, Forever: Similar to While/Wend, but the condition is at the end and will only loop if the condition is false.
|
|
// - Exit: Exit from any currently active loops. I guess this allows leaving Repeat/Forever combinations.
|
|
// - True, False: True and False. What, did you expect something else?
|
|
// - Stop: Pause the program for the debugger, if there happens to be one.
|
|
// - End: Terminate the program.
|
|
// - Goto: Jump to a specific label, without setting the return address.
|
|
// - Gosub, Return: Jump to a specific label (subroutine), setting the return address appropriately, and Return from it eventually.
|
|
// - Function, Return, End Function: Defines a function, and allows returning values. Yes, I know, End itself terminates the program, this is a special case. Thanks younger Sibly.
|
|
// - And, Or, Not: Logical operator, self-explanatory really.
