C Language Features
HI-TECH PICC-18 STD supports a number of special features and extensions to the C language
which are designed to ease the task of producing ROM-based applications. This chapter documents
the compiler options and special language features which are specific to the Microchip PIC 18 family
of processors.
3.1 ANSI Standard Issues
3.1.1 Divergence from the ANSI C Standard
HI-TECH PICC-18 STD diverges from the ANSI C standard in one area: function recursion.
Due to the PIC18’s hardware limitations of no easily-usable stack and limited memory, function
recursion is unsupported.
3.1.2 Implementation-defined behaviour
Certain sections of the ANSI standard have implementation-defined behaviour. This means that the
exact behaviour of some C code can vary from compiler to compiler. Throughout this manual are
sections describing how the HI-TECH PICC-18 STD compiler behaves in such situations.
3.2 Processor-related Features
HI-TECH PICC-18 STD has many features which relate directly to the PIC18 family of processors.
These are detailed in the following sections.
