Other directives

The built-in #defines are used to support the #IFDEF command set are as follows. The table also shows which #defines are supported as string in HSerPrint, SerPrint and other string related commands.

Directive	Description	Output Usage	Returns
ChipADC	String	#IFDEF & Output commands	The number of A/D inputs on the current chip
ChipEEprom	Number	#IFDEF & Output commands	The number of Bytes in EEPROM memmory
ChipIO	String	#IFDEF & Output commands	The number of general purpose IO pins
ChipMHz	String	#IFDEF & Output commands	The microcontroller clock speed
ChipName	Number	#IFDEF Only	The microcontroller type
ChipNameStr	String	#IFDEF & Output commands	The microcontroller name
ChipPins	Number	#IFDEF & Output commands	The number of microcontroller pins.
ChipReserveHighProg	Number	#Scripts, #IFDEF & Output commands	The value of the words reserved
ChipProgrammerNameStr	String	Name of the chip type to be used by a programmer	The psuedo microcontroller type
ChipRam	Number	#IFDEF & Output commands	The RAM size
ChipFamily	Number	#IFDEF & Output commands	See the table below
ChipWords	Number	#IFDEF & Output commands	The number of WORDS in Flash memmory
Var()	Function	Not applicable	True if a register is declared (or false if not declared) in the currently specficied microcontroller’s .dat file. Var(register_name)
NoVar()	Function	Not applicable	True if a register is NOT declared (or false if declared) in the currently specficied microcontroller’s .dat file. NoVar(register_name)
Bit()	Function	Not applicable	True if a bit is declared (or false if not declared) in the currently specficied microcontroller’s .dat file. Bit(bit_name)
NoBit()	Function	Not applicable	True if a bit is NOT declared (or false if declared) in the currently specficied microcontroller’s .dat file. NoBit(bit_name)
Allof()	Function	Not applicable	True if all defines are declared: AllOf(define1, define2, …)
OneOf()	Function	Not applicable	True if one of the defines is declared: OneOf(define1, define2, …)

The table below shows two special directives that support the mapping for one variable or bit to anoher variable or bit. This is useful when creating portable code or libraries to ensure Great Cow BASIC

Directive	Explanation	Usage
#samebit	The compiler checks each item in the list to see which ones are implemented on the current microcontroller. If any of the bits do not exist, the compiler will create a constant mapping to the name of the first parameter in the list of parameters that does exist. + If none of the bits exist the no constant is created.	#samebit PLLEN, SPLLEN, SPLLMULT     Set SPLLEN On
#samevar	The compiler checks each item in the list to see which ones are implemented on the current microcontroller. If any of the variables do not exist, the compiler will create a constant mapping to the name of the first parameter in the list of parameters that does exist. + If none of the variables exist the no constant is created.	#samevar CMCON, CMCON0, CMCONbob   #ifdef Var(CMCONbob)       CMCONbob = 7   #endif   Compiles to:   ;CMCONbob = 7   movlw 7   movwf CMCON,ACCESS

This table shows the ChipFamily constants mapped to the microcontroller architecture.
