SW006011 - 

The MPLAB® C18 compiler is a full-featured ANSI compliant C compiler for the PIC18 family of PIC® microcontrollers 8-bit MCUs. MPLAB C18 is a 32-bit Windows® console application as well as a fully integrated component of Microchip's MPLAB IDE Integrated Development Environment, allowing source level debugging with the MPLAB ICE In-Circuit Emulator, the MPLAB ICD 2 In-Circuit Debugger, and the MPLAB SIM simulator.
Projects, compiler switches and linker customizations can be controlled completely within MPLAB IDE to provide a full graphical front end for this powerful compiler. Text errors in source code and breakpoints instantly switch to corresponding lines in the proper file and watch windows show data structures with defined data types, including floating point, arrays and structures.
