Language Extensions

There is a language extension in the Compiler for ANSI-C. You can use keywords to qualify pointers in order to distinguish them, or to mark interrupt routines.

The Compiler supports the following non-ANSI compliant keywords (see Backend if they are supported and for their semantics):

• Pointer Qualifiers
  
• Special Keywords
  
• Binary Constants (0b)
  
• Hexadecimal constants ($)
  
• #warning directive
  
• Global Variable Address Modifier (@address)
  
• Variable Allocation using @"SegmentName"
  
• The __far Keyword
  
• __near Keyword
  
• Compatibility
  
• __alignof__ keyword
  
• __va_sizeof__ keyword
  
• interrupt keyword
  
• __asm Keyword
