Expressions for #if and #elif are numeric unsigned 32-bit integers. The supported operators are:

+ - | &              (high precedence) 
== > >= < <= || &&   (low precedence)

Parenthesis are not supported.

#defineN evaluates the specified Expression and then assigns the result to Symbol. By contrast, #define merely associates one string with another without any interpretation or evaluation.

RTLoc will expand symbols defined with #define/#defineN or RTLoc's command line option -D. However, such expansions cannot change the number of tokens. A single token is always expanded to a new single token, whereby numeric expressions are considered a single token. The only exception are tokens generated through the token pasting operator ##. For example, the code:

#define Test Left ## Right 
#error Test

Would print the text:

Error: LeftRight

The following symbols are predefined:

OUTNAME     = <base output directory and file name without extension> 
APPLICATION = <Application name specified on RTLoc command line> 
RTT32_VER   = <RTTarget-32 version multiplied by 100> 
RTLOC       = TRUE 
TRUE        = 1 
FALSE       = 0

#ifsection and #elifsection evaluate to true if section SectionName exists in the .EXE or .DLL specified by ModuleName. If no ModuleName is given, the main .EXE file is assumed.
