BlitzMax/Language/Conditional Compiling

Conditional compiling allows you to turn compiling on or off from within your program depending on the environment the program is being compiled for.

Conditional compiling works a bit like an If statement, but takes the form:

?Identifier

The ? must appear at the start of a new line, and Identifier should be one of the following:

Name	Meaning
Debug	True if program is being compiled in debug mode.
Threaded	True if program is being compiled in threaded mode.
Win32	True if program is being compiled for the Windows operating system.
MacOS	True if program is being compiled for the MacOS operating system.
Linux	True if program is being compiled for the Linux operating system.
X86	True if program is being compiled for the Intel CPU.
PPC	True if program is being compiled for the PowerPC CPU.
MacOSX86	True if program is being compiled for an Intel Mac.
MacOSPPC	True if program is being compiled for a PowerPC Mac.
BigEndian	True if program is being compiled for a big endian CPU.
LittleEndian	True if program is being compiled for a little endian CPU.

Identifier may also be preceded by Not to invert the result.

An ? on its own always turns compiling on.

For example:

?Debug
'Any code here is only compiled in debug mode.
?Not Debug
'Any code here is only compiled in release mode.
?
'Code here is always compiled.
